What it does

• OpenAI-compatible local TTS. speech-server exposes POST /v1/audio/speech with OpenAI model aliases, native and generic voices, language and speed controls, WAV/PCM output, and optional bearer authentication.
• Windows release package. a self-contained x64 ZIP ships the server, ONNX CLI tools, speech.dll, ONNX Runtime, and a native PowerShell model downloader; CI builds and smoke-tests the extracted archive.
• DeepFilterNet3 parity. native libdf-compatible STFT scaling, ERB/complex normalization, deep filtering, overlap-add, and 480-sample delay compensation restore reference DSP behavior.
• Streaming Pocket TTS. the ONNX backend emits fixed 80 ms frames with a bounded decoder cache and an opt-in model-backed round-trip harness.
• Correct Silero v5 context. every ONNX inference now receives the graph's required 64-sample left context.
