-
-## Background
-
-SYCL is a higher-level programming model to improve programming productivity on various hardware accelerators—such as CPUs, GPUs, and FPGAs. It is a single-source embedded domain-specific language based on pure C++17.
-
-oneAPI is a specification that is open and standards-based, supporting multiple architecture types including but not limited to GPU, CPU, and FPGA. The spec has both direct programming and API-based programming paradigms.
-
-Intel uses the SYCL as direct programming language to support CPU, GPUs and FPGAs.
-
-To avoid  re-inventing the wheel, this code refers other code paths in llama.cpp (like OpenBLAS, cuBLAS, CLBlast). We use a open-source tool [SYCLomatic](https://github.com/oneapi-src/SYCLomatic) (Commercial release [Intel® DPC++ Compatibility Tool](https://www.intel.com/content/www/us/en/developer/tools/oneapi/dpc-compatibility-tool.html)) migrate to SYCL.
-
-The whisper.cpp for SYCL is used to support Intel GPUs.
-
-For Intel CPU, recommend to use whisper.cpp for X86 (Intel MKL build).
-

-1. Install Intel GPU driver.
-
-a. Please install Intel GPU driver by official guide: [Install GPU Drivers](https://dgpu-docs.intel.com/driver/installation.html).
-
-Note: for iGPU, please install the client GPU driver.
-
-b. Add user to group: video, render.
-
-```
-sudo usermod -aG render username
-sudo usermod -aG video username
-```
-
-Note: re-login to enable it.
-
-c. Check
-
-```
-sudo apt install clinfo

-[opencl:gpu:2] Intel(R) OpenCL Graphics, Intel(R) Arc(TM) A770 Graphics OpenCL 3.0 NEO  [23.30.26918.50]
-[ext_oneapi_level_zero:gpu:0] Intel(R) Level-Zero, Intel(R) Arc(TM) A770 Graphics 1.3 [1.3.26918]
-
-```
-
-2. Build locally:
-
-```
-mkdir -p build
-cd build
-source /opt/intel/oneapi/setvars.sh
-
-#for FP16
-#cmake .. -DWHISPER_SYCL=ON -DCMAKE_C_COMPILER=icx -DCMAKE_CXX_COMPILER=icpx -DWHISPER_SYCL_F16=ON 
-
-#for FP32
-cmake .. -DWHISPER_SYCL=ON -DCMAKE_C_COMPILER=icx -DCMAKE_CXX_COMPILER=icpx
-
-#build example/main only
-#cmake --build . --config Release --target main
-
-#build all binary
-cmake --build . --config Release -v
-
-```
-
-or
-
-```
-./examples/sycl/build.sh
-```
-
-Note:
-
-- By default, it will build for all binary files. It will take more time. To reduce the time, we recommend to build for **example/main** only.
-
-### Run
-
-1. Put model file to folder **models**
-
-2. Enable oneAPI running environment
-
-```
-source /opt/intel/oneapi/setvars.sh
-```
-
-3. List device ID
-
-Run without parameter:
-
-```
-./build/bin/ls-sycl-device
-
-or
-
-./build/bin/main
-```
-
-Check the ID in startup log, like:
-
-```
-found 4 SYCL devices:
-  Device 0: Intel(R) Arc(TM) A770 Graphics,	compute capability 1.3,
-    max compute_units 512,	max work group size 1024,	max sub group size 32,	global mem size 16225243136

-    max compute_units 512,	max work group size 1024,	max sub group size 32,	global mem size 16225243136
-
-```
-
-|Attribute|Note|
-|-|-|
-|compute capability 1.3|Level-zero running time, recommended |
-|compute capability 3.0|OpenCL running time, slower than level-zero in most cases|
-
-4. Set device ID and execute whisper.cpp
-
-Set device ID = 0 by **GGML_SYCL_DEVICE=0**
-
-```
-GGML_SYCL_DEVICE=0 ./build/bin/main -m models/ggml-base.en.bin -f samples/jfk.wav
-```
-or run by script:
-
-```
-./examples/sycl/run_whisper.sh
-```
-
-
-
-5. Check the device ID in output
-
-Like:
-```
-Using device **0** (Intel(R) Arc(TM) A770 Graphics) as main device
-```
-
-

-
-## Known Issue
-
-- Error:  `error while loading shared libraries: libsycl.so.7: cannot open shared object file: No such file or directory`.
-
-  Miss to enable oneAPI running environment.
-
-  Install oneAPI base toolkit and enable it by: `source /opt/intel/oneapi/setvars.sh`.
-
-
-- Hang during startup
-
-  llama.cpp use mmap as default way to read model file and copy to GPU. In some system, memcpy will be abnormal and block.
-
-  Solution: add **--no-mmap**.
-
-## Todo
-
-- Support to build in Windows.
-
-- Support multiple cards.

-# Go bindings for Whisper
-
-This package provides Go bindings for whisper.cpp. They have been tested on:
-
-  * Darwin (OS X) 12.6 on x64_64
-  * Debian Linux on arm64
-  * Fedora Linux on x86_64
-
-The "low level" bindings are in the `bindings/go` directory and there is a more
-Go-style package in the `bindings/go/pkg/whisper` directory. The most simple usage
-is as follows:
-
-```go
-import (
-	"github.com/ggerganov/whisper.cpp/bindings/go/pkg/whisper"
-)
-
-func main() {
-	var modelpath string // Path to the model
-	var samples []float32 // Samples to process
-
-	// Load the model
-	model, err := whisper.New(modelpath)
-	if err != nil {
-		panic(err)
-	}
-	defer model.Close()
-
-	// Process samples
-	context, err := model.NewContext()
-	if err != nil {
-		panic(err)
-	}
-	if err := context.Process(samples, nil, nil, nil); err != nil {
-		return err
-	}
-
-	// Print out the results
-	for {
-		segment, err := context.NextSegment()
-		if err != nil {
-			break
-		}
-		fmt.Printf("[%6s->%6s] %s\n", segment.Start, segment.End, segment.Text)
-	}
-}
-```
-
-## Building & Testing
-
-In order to build, you need to have the Go compiler installed. You can get it from [here](https://golang.org/dl/). Run the tests with:
-
-```bash
-git clone https://github.com/ggml-org/whisper.cpp.git
-cd whisper.cpp/bindings/go
-make test
-```
-
-This will compile a static `libwhisper.a` in a `build` folder, download a model file, then run the tests. To build the examples:
-
-```bash
-make examples
-```
-
-To build using cuda support add `GGML_CUDA=1`:
-
-```bash
-GGML_CUDA=1 make examples
-```
-
-The examples are placed in the `build` directory. Once built, you can download all the models with the following command:
-
-```bash
-./build/go-model-download -out models
-```
-
-And you can then test a model against samples with the following command:
-
-```bash
-./build/go-whisper -model models/ggml-tiny.en.bin samples/jfk.wav
-```
-
-## Using the bindings
-
-To use the bindings in your own software,
-
-  1. Import `github.com/ggerganov/whisper.cpp/bindings/go/pkg/whisper` (or `github.com/ggerganov/whisper.cpp/bindings/go` into your package;
-  2. Compile `libwhisper.a` (you can use `make whisper` in the `bindings/go` directory);
-  3. Link your go binary against whisper by setting the environment variables `C_INCLUDE_PATH` and `LIBRARY_PATH`
-     to point to the `whisper.h` file directory and `libwhisper.a` file directory respectively.
-
-Look at the `Makefile` in the `bindings/go` directory for an example.
-
-The API Documentation:
-
-  * https://pkg.go.dev/github.com/ggerganov/whisper.cpp/bindings/go
-  * https://pkg.go.dev/github.com/ggerganov/whisper.cpp/bindings/go/pkg/whisper
-
-Getting help:
-
-  * Follow the discussion for the go bindings [here](https://github.com/ggml-org/whisper.cpp/discussions/312)

-# Java JNI bindings for Whisper
-
-This package provides Java JNI bindings for whisper.cpp. They have been tested on:
-
-  * <strike>Darwin (OS X) 12.6 on x64_64</strike>
-  * Ubuntu on x86_64
-  * Windows on x86_64
-
-The "low level" bindings are in `WhisperCppJnaLibrary`. The most simple usage is as follows:
-
-JNA will attempt to load the `whispercpp` shared library from:
-
-- jna.library.path
-- jna.platform.library
-- ~/Library/Frameworks
-- /Library/Frameworks
-- /System/Library/Frameworks
-- classpath
-
-```java
-import io.github.ggerganov.whispercpp.WhisperCpp;
-
-public class Example {
-
-    public static void main(String[] args) {
-        WhisperCpp whisper = new WhisperCpp();
-        // By default, models are loaded from ~/.cache/whisper/ and are usually named "ggml-${name}.bin"
-        // or you can provide the absolute path to the model file.
-        long context = whisper.initContext("base.en");
-        try {
-            var whisperParams = whisper.getFullDefaultParams(WhisperSamplingStrategy.WHISPER_SAMPLING_GREEDY);
-            // custom configuration if required
-            whisperParams.temperature_inc = 0f;
-
-            var samples = readAudio(); // divide each value by 32767.0f
-            whisper.fullTranscribe(whisperParams, samples);
-
-            int segmentCount = whisper.getTextSegmentCount(context);
-            for (int i = 0; i < segmentCount; i++) {
-                String text = whisper.getTextSegment(context, i);
-                System.out.println(segment.getText());
-            }
-        } finally {
-             whisper.freeContext(context);
-        }
-     }
-}
-```
-
-## Building & Testing
-
-In order to build, you need to have the JDK 8 or higher installed. Run the tests with:
-
-```bash
-git clone https://github.com/ggml-org/whisper.cpp.git
-cd whisper.cpp/bindings/java
-
-./gradlew build
-```
-
-You need to have the `whisper` library in your [JNA library path](https://java-native-access.github.io/jna/4.2.1/com/sun/jna/NativeLibrary.html). On Windows the dll is included in the jar and you can update it:
-
-```bash
-copy /y ..\..\build\bin\Release\whisper.dll build\generated\resources\main\win32-x86-64\whisper.dll
-```
-
-
-## License
-
-The license for the Java bindings is the same as the license for the rest of the whisper.cpp project, which is the MIT License. See the `LICENSE` file for more details.

-#   Gradle start up script for POSIX generated by Gradle.
-#
-#   Important for running:
-#
-#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
-#       noncompliant, but you have some other compliant shell such as ksh or
-#       bash, then to run this script, type that shell name before the whole
-#       command line, like:
-#
-#           ksh Gradle
-#
-#       Busybox and similar reduced shells will NOT work, because this script
-#       requires all of these POSIX shell features:
-#         * functions;
-#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
-#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
-#         * compound commands having a testable exit status, especially «case»;
-#         * various built-in commands including «command», «set», and «ulimit».
-#
-#   Important for patching:
-#
-#   (2) This script targets any POSIX shell, so it avoids extensions provided
-#       by Bash, Ksh, etc; in particular arrays are avoided.
-#
-#       The "traditional" practice of packing multiple parameters into a
-#       space-separated string is a well documented source of bugs and security
-#       problems, so this is (mostly) avoided, by progressively accumulating
-#       options in "$@", and eventually passing that to Java.
-#
-#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
-#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
-#       see the in-line comments for details.
-#
-#       There are tweaks for specific operating systems such as AIX, CygWin,
-#       Darwin, MinGW, and NonStop.
-#
-#   (3) This script is generated from the Groovy template
-#       https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
-#       within the Gradle project.

-# whisper.cpp
-
-Node.js package for Whisper speech recognition
-
-Package: https://www.npmjs.com/package/whisper.cpp
-
-## Details
-
-The performance is comparable to when running `whisper.cpp` in the browser via WASM.
-
-The API is currently very rudimentary: [bindings/javascript/emscripten.cpp](/bindings/javascript/emscripten.cpp)
-
-For sample usage check [tests/test-whisper.js](/tests/test-whisper.js)
-
-## Package building + test
-
-```bash
-# load emscripten
-source /path/to/emsdk/emsdk_env.sh
-
-# clone repo
-git clone https://github.com/ggerganov/whisper.cpp
-cd whisper.cpp
-
-# grab base.en model
-./models/download-ggml-model.sh base.en
-
-# prepare PCM sample for testing
-ffmpeg -i samples/jfk.wav -f f32le -acodec pcm_f32le samples/jfk.pcmf32
-
-# build
-mkdir build-em && cd build-em
-emcmake cmake .. && make -j
-
-# run test
-node ../tests/test-whisper.js
-
-# For Node.js versions prior to v16.4.0, experimental features need to be enabled:
-node --experimental-wasm-threads --experimental-wasm-simd ../tests/test-whisper.js
-
-# publish npm package
-make publish-npm
-```
-
-## Sample run
-
-```text

-
-![whisper.cpp](https://user-images.githubusercontent.com/1991296/235238348-05d0f6a4-da44-4900-a1de-d0707e75b763.jpeg)
-
-Ruby bindings for [whisper.cpp][], an interface of automatic speech recognition model.
-
-Installation
-------------
-
-Install the gem and add to the application's Gemfile by executing:
-
-    $ bundle add whispercpp
-
-If bundler is not being used to manage dependencies, install the gem by executing:
-
-    $ gem install whispercpp
-
-You can pass build options for whisper.cpp, for instance:
-
-    $ bundle config build.whispercpp --enable-ggml-cuda
-
-or,
-
-    $ gem install whispercpp -- --enable-ggml-cuda
-
-See whisper.cpp's [README](https://github.com/ggml-org/whisper.cpp/blob/master/README.md) for available options. You need convert options present the README to Ruby-style options, for example:
-
-Boolean options:
-
-* `-DGGML_BLAS=1` -> `--enable-ggml-blas`
-* `-DWHISER_COREML=OFF` -> `--disable-whisper-coreml`
-
-Argument options:
-
-* `-DGGML_CUDA_COMPRESSION_MODE=size` -> `--ggml-cuda-compression-mode=size`
-
-Combination:
-
-* `-DGGML_CUDA=1 -DCMAKE_CUDA_ARCHITECTURES="86"` -> `--enable-ggml-cuda --cmake_cuda-architectures="86"`
-
-For boolean options like `GGML_CUDA`, the README says `-DGGML_CUDA=1`. You need strip `-D`, prepend `--enable-` for `1` or `ON` (`--disable-` for `0` or `OFF`) and make it kebab-case: `--enable-ggml-cuda`.  
-For options which require arguments like `CMAKE_CUDA_ARCHITECTURES`, the README says `-DCMAKE_CUDA_ARCHITECTURES="86"`. You need strip `-D`, prepend `--`, make it kebab-case, append `=` and append argument: `--cmake-cuda-architectures="86"`.
-
-Usage
------
-
-```ruby
-require "whisper"
-
-whisper = Whisper::Context.new("base")
-
-params = Whisper::Params.new(
-  language: "en",
-  offset: 10_000,
-  duration: 60_000,
-  max_text_tokens: 300,
-  translate: true,
-  print_timestamps: false,
-  initial_prompt: "Initial prompt here."
-)
-
-whisper.transcribe("path/to/audio.wav", params) do |whole_text|
-  puts whole_text
-end
-
-```
-
-### Preparing model ###
-
-Some models are prepared up-front:
-
-You also can use shorthand for pre-converted models:
-
-```ruby
-whisper = Whisper::Context.new("base.en")
-```
-
-You can see the list of prepared model names by `Whisper::Model.pre_converted_models.keys`:
-
-```ruby
-puts Whisper::Model.pre_converted_models.keys
-# tiny
-# tiny.en
-# tiny-q5_1
-# tiny.en-q5_1
-# tiny-q8_0
-# base
-# base.en
-# base-q5_1
-# base.en-q5_1
-# base-q8_0
-#   :
-#   :
-```
-
-You can also retrieve each model:
-
-```ruby
-base_en = Whisper::Model.pre_converted_models["base.en"]
-whisper = Whisper::Context.new(base_en)
-```
-
-At first time you use a model, it is downloaded automatically. After that, downloaded cached file is used. To clear cache, call `#clear_cache`:
-
-```ruby
-Whisper::Model.pre_converted_models["base"].clear_cache
-```
-
-You can also use local model files you prepared:
-
-```ruby
-whisper = Whisper::Context.new("path/to/your/model.bin")
-```
-
-Or, you can download model files:
-
-```ruby
-whisper = Whisper::Context.new("https://example.net/uri/of/your/model.bin")
-# Or
-whisper = Whisper::Context.new(URI("https://example.net/uri/of/your/model.bin"))
-```
-
-See [models][] page for details.
-
-### Preparing audio file ###
-
-Currently, whisper.cpp accepts only 16-bit WAV files.
-
-### Voice Activity Detection (VAD) ###
-
-Support for Voice Activity Detection (VAD) can be enabled by setting `Whisper::Params`'s `vad` argument to `true` and specifying VAD model:
-
-```ruby
-Whisper::Params.new(
-  vad: true,
-  vad_model_path: "silero-v5.1.2",
-  # other arguments...
-)
-```
-
-When you pass the model name (`"silero-v5.1.2"`) or URI (`https://huggingface.co/ggml-org/whisper-vad/resolve/main/ggml-silero-v5.1.2.bin`), it will be downloaded automatically.
-Currently, "silero-v5.1.2" is registered as pre-converted model like ASR models. You also specify file path or URI of model.
-
-If you need configure VAD behavior, pass params for that:
-
-```ruby
-Whisper::Params.new(
-  vad: true,
-  vad_model_path: "silero-v5.1.2",
-  vad_params: Whisper::VAD::Params.new(
-    threshold: 1.0, # defaults to 0.5
-    min_speech_duration_ms: 500, # defaults to 250
-    min_silence_duration_ms: 200, # defaults to 100
-    max_speech_duration_s: 30000, # default is FLT_MAX,
-    speech_pad_ms: 50, # defaults to 30
-    samples_overlap: 0.5 # defaults to 0.1
-  ),
-  # other arguments...
-)
-```
-
-For details on VAD, see [whisper.cpp's README](https://github.com/ggml-org/whisper.cpp?tab=readme-ov-file#voice-activity-detection-vad).
-
-### Output ###
-
-whispercpp supports SRT and WebVTT output:
-
-```ruby
-puts whisper.transcribe("path/to/audio.wav", Whisper::Params.new).to_webvtt
-# =>
-WEBVTT
-
-1
-00:00:00.000 --> 00:00:03.860
- My thought I have nobody by a beauty and will as you poured.
-
-2
-00:00:03.860 --> 00:00:09.840
- Mr. Rochester is sub in that so-don't find simplest, and devoted about, to let might in
-
-3
-00:00:09.840 --> 00:00:09.940
- a
-
-```
-
-You may call `#to_srt`, too
-
-
-API
----
-
-### Transcription ###
-
-By default, `Whisper::Context#transcribe` works in a single thread. You can make it work in parallel by passing `n_processors` option:
-
-```ruby
-whisper.transcribe("path/to/audio.wav", params, n_processors: Etc.nprocessors)
-```
-
-Note that transcription occasionally might be low accuracy when it works in parallel.
-
-### Segments ###
-
-Once `Whisper::Context#transcribe` called, you can retrieve segments by `#each_segment`:
-
-```ruby
-def format_time(time_ms)
-  sec, decimal_part = time_ms.divmod(1000)
-  min, sec = sec.divmod(60)
-  hour, min = min.divmod(60)
-  "%02d:%02d:%02d.%03d" % [hour, min, sec, decimal_part]
-end
-
-whisper
-  .transcribe("path/to/audio.wav", params)
-  .each_segment.with_index do |segment, index|
-    line = "[%{nth}: %{st} --> %{ed}] %{text}" % {
-      nth: index + 1,
-      st: format_time(segment.start_time),
-      ed: format_time(segment.end_time),
-      text: segment.text
-    }
-    line << " (speaker turned)" if segment.speaker_turn_next?
-    puts line
-  end
-
-```
-
-You can also add hook to params called on new segment:
-
-```ruby
-# Add hook before calling #transcribe
-params.on_new_segment do |segment|
-  line = "[%{st} --> %{ed}] %{text}" % {
-    st: format_time(segment.start_time),
-    ed: format_time(segment.end_time),
-    text: segment.text
-  }
-  line << " (speaker turned)" if segment.speaker_turn_next?
-  puts line
-end
-
-whisper.transcribe("path/to/audio.wav", params)
-
-```
-
-### Models ###
-
-You can see model information:
-
-```ruby
-whisper = Whisper::Context.new("base")
-model = whisper.model
-
-model.n_vocab # => 51864
-model.n_audio_ctx # => 1500

-### Logging ###
-
-You can set log callback:
-
-```ruby
-prefix = "[MyApp] "
-log_callback = ->(level, buffer, user_data) {
-  case level
-  when Whisper::LOG_LEVEL_NONE
-    puts "#{user_data}none: #{buffer}"
-  when Whisper::LOG_LEVEL_INFO
-    puts "#{user_data}info: #{buffer}"
-  when Whisper::LOG_LEVEL_WARN
-    puts "#{user_data}warn: #{buffer}"
-  when Whisper::LOG_LEVEL_ERROR
-    puts "#{user_data}error: #{buffer}"
-  when Whisper::LOG_LEVEL_DEBUG
-    puts "#{user_data}debug: #{buffer}"
-  when Whisper::LOG_LEVEL_CONT
-    puts "#{user_data}same to previous: #{buffer}"
-  end
-}
-Whisper.log_set log_callback, prefix
-```
-
-Using this feature, you are also able to suppress log:
-
-```ruby
-Whisper.log_set ->(level, buffer, user_data) {
-  # do nothing
-}, nil
-Whisper::Context.new("base")
-```
-
-### Low-level API to transcribe ###
-
-You can also call `Whisper::Context#full` and `#full_parallel` with a Ruby array as samples. Although `#transcribe` with audio file path is recommended because it extracts PCM samples in C++ and is fast, `#full` and `#full_parallel` give you flexibility.
-
-```ruby
-require "whisper"
-require "wavefile"
-
-reader = WaveFile::Reader.new("path/to/audio.wav", WaveFile::Format.new(:mono, :float, 16000))
-samples = reader.enum_for(:each_buffer).map(&:samples).flatten
-
-whisper = Whisper::Context.new("base")
-whisper
-  .full(Whisper::Params.new, samples)
-  .each_segment do |segment|
-    puts segment.text
-  end
-```
-
-The second argument `samples` may be an array, an object with `length` and `each` method, or a MemoryView. If you can prepare audio data as C array and export it as a MemoryView, whispercpp accepts and works with it with zero copy.
-
-Development
------------
-
-    % git clone https://github.com/ggml-org/whisper.cpp.git
-    % cd whisper.cpp/bindings/ruby
-    % rake test
-
-First call of `rake test` builds an extension and downloads a model for testing. After that, you add tests in `tests` directory and modify `ext/ruby_whisper.cpp`.
-
-If something seems wrong on build, running `rake clean` solves some cases.
-
-### Need help ###
-
-* Windows support
-* Refinement of C/C++ code, especially memory management
