Updated Whisper.net from 1.7.0 to 1.9.1.

Release notes

Sourced from Whisper.net's releases.

1.9.1

Highlights

  • Added Voice Activity Detection (VAD) support, including WhisperVadFactory, WhisperVadProcessor, builder/options APIs, VAD segment data, functional/unit tests, and a new examples/Vad sample.
  • Added Silero VAD model support to WhisperGgmlDownloader, including a dedicated SileroVadType enum and downloader test coverage.
  • Added the Whisper.net.Runtime.Cuda12 runtime packages for Windows and Linux, with runtime-loader support and dependency-checker updates.
  • Improved language detection by exposing whisper_lang_id() and adding candidate-based DetectLanguageWithProbability support.
  • Bumped whisper.cpp through 1.8.5 and refreshed native build/test workflows.
  • Simplified sampling strategy configuration by removing IWhisperSamplingStrategyBuilder.
  • Improved WhisperProcessor cancellation/instance handling and native failure/error-level propagation.

Compatibility & tooling

  • Enabled XML documentation output for build/package artifacts.
  • Included symbols in NuGet packages.
  • Updated GitHub Actions and runner versions across managed, native, MAUI, NoAVX, CodeQL, package, and push workflows.
  • Added repository Copilot instructions and reusable validation skills for managed API, native runtime, runtime-loading, package/release, MAUI, NoAVX, and test-model workflows.
  • Updated Blazor reconnection handling and refreshed example package versions.

Dependency updates

  • Updated Microsoft.Extensions.AI.Abstractions through 10.2.0.
  • Updated Microsoft.Bcl.AsyncInterfaces through 10.0.7.
  • Updated Microsoft.AspNetCore.Components.WebAssembly and Server through 10.0.5.
  • Updated Microsoft.Extensions.Logging.Debug to 10.0.7.
  • Updated NAudio to 2.3.0.
  • Updated Microsoft.DotNet.XHarness.TestRunners.Xunit prerelease and coverlet.collector 10.0.0.

1.9.0

Highlights

  • .NET 10 support across the library, tests, and CI (including refreshed MAUI test suite and runner images).
  • New ISpeechToTextClient implementation (WhisperSpeechToTextClient) for Microsoft.Extensions.AI consumers.
  • Native interop hardened (UTF-8 handling, safer marshaling) and whisper.cpp bumped to 1.8.2 with prompt-carry fix; added dedicated Metal runtime and static iOS libs.

New features & capabilities

  • Added Microsoft.Extensions.AI-compatible speech-to-text client plus factory/extensions, demo integration, and thorough unit coverage.
  • Introduced WaveParserOptions with a permissive parsing mode for less strictly formatted WAV inputs.
  • Updated whisper.cpp to 1.8.2 and carry-initial-prompt handling to avoid reuse-related memory issues.
  • Shipped a Metal runtime NuGet and switched iOS builds to static libs to simplify mobile linking and app store deployment.
  • Upgraded CUDA tooling/runtime to 13.0.1 for GPU builds.

Bug fixes & stability

  • Native failures now surface as WhisperProcessingException with clearer error reporting and cancellation behavior.
  • Fixed a concurrent collection access crash in WhisperProcessor.
  • Addressed native resource handling issues (CoreML library loading, OpenVINO path string lifetime) and tightened interop safety.
  • Test reliability improvements (model download in fixtures, reduced obsolete target matrices).
  • Dependency and security hygiene updates via routine package bumps.

Compatibility & tooling

  • Primary targets and CI pipelines updated for .NET 10; test projects and runners aligned with the new SDK images.
  • MAUI test project migrated to a .NET 10-ready layout with refreshed device profiles and runner configuration.
  • Added CUDA, CodeQL, and native build workflow updates to match new toolchain versions.

What's Changed

1.8.1

Fixes

This release represents 2 small fixes for:

  • NoAVX Runtime was missing artifact on Windows
  • Vulkan Runtime was crashing caused by stack overflow on some hardware

Changelog

Full Changelog: sandrohanea/whisper.net@1.8.0...1.8.1

1.8.0

Whisper.net 1.8.0 brings numerous improvements, breaking changes, and enhanced developer experience. Buckle up — this one's big.

🔁 Versioning Change

Whisper.net follows semantic versioning.

Starting from version `1.8.0`, Whisper.net no longer mirrors the versioning of `whisper.cpp`, which now uses commit-based versions (e.g., b2254, b2255).

To identify the `whisper.cpp` version used in a Whisper.net release, check the `whisper.cpp` submodule. The commit hash in the release tag maps directly to the `whisper.cpp` version.

🛠 Breaking Changes

📦 WhisperGgmlDownloader is now instantiable

  • No longer static. Introduced a WhisperGgmlDownloader.Default instance for default usage.
  • Allows injecting custom HttpClient for authenticated/controlled requests (e.g., Hugging Face tokens).

Old usage:

await WhisperGgmlDownloader.GetGgmlModelAsync(...);

New usage:

await WhisperGgmlDownloader.Default.GetGgmlModelAsync(...);

🧠 WhisperLogLevel Reordered

// Old
None = 0,
Info = 1,
Warning = 2,
Error = 3,
Debug = 4,
Cont = 5

// New
 ... (truncated)

## 1.7.4

We're thrilled to announce the release of whisper.net 1.7.4, featuring a host of improvements and new functionalities.

## Key Features and Changes

 - Custom Alignment Heads for DTW: Now, you can define custom alignment heads for Dynamic Time Warping (DTW), enhancing the accuracy of speech-to-text alignment in various scenarios.
 - Upgrade to `Whisper.cpp 1.7.3` which included multiple updates and fixes:
      - `WithNoSpeechThreshold` Support: This allows for better handling of silent segments in audio, improving transcription accuracy.
      - Performance Enhancements: Significant improvements, especially on the Metal runtime for macOS, ensuring faster processing times.
      - Library Split: The native libraries are now split into multiple files (`libggml-whisper`, `libggml-base-whisper`, etc.), allowing for more modular use and easier updates.
  - MAUI App Testing for iOS: Added tests for MAUI applications on iOS, ensuring better support for cross-platform development. 🚀
  - Whisper Factory Options: Introduced new options at the WhisperFactory level for more granular control over configurations, previously managed through a singleton at the library level (RuntimeOptions). This improves flexibility and maintainability. Note: RuntimeOptions are still available but only to configure the way how the native runtime is being loaded.
  - The continuous recognition example has been deprecated in favor of [EchoSharp](https://github.com/sandrohanea/echosharp), which provides a more robust and up-to-date demonstration of continuous speech recognition capabilities.
  - FIxed an issue where the native library couldn't be auto-loaded on systems that are not providing any command line arguments (like godot)
