[Unreleased]

Runtime domain customization for streaming speech-to-text: pass keyterms to bias decoding towards jargon, or context to find the terms in a passage of text. See Domain Customization.
Documentation has been reorganized in mkdocs style, with one file per section rather than everything in one large README.md. These docs are also available at moonshine.readthedocs.io.

moonshine_load_transcriber_from_memory_files() rejects an unrecognized filename key with MOONSHINE_ERROR_INVALID_ARGUMENT, naming it, instead of dropping it silently and reporting the file as missing.

Meeting Notes no longer freezes for seconds when returning to its tab during a long recording: capture audio is batched and the main thread yields while catching up.
Core library builds no longer write into the source tree, where targets clobbered each other's archives, and the wheels, archives and Android debug variant are now optimized rather than debug builds (8-15% faster streaming on a Pixel 10a).

Speculative decoding for streaming speech-to-text, on by default. Streaming re-decodes verify the previous hypothesis and continue from the first mismatch instead of restarting from BOS, cutting live latency on several platforms (for example Medium Streaming on MacBook Pro from ~103ms to ~74ms). Disable with use_speculative_decoding=false.
AgentFlow.otherwise() — a callback for speech that matched no trigger and no waiting prompt, so dictation-style UIs can take free-form lines without treating them as failed commands.
Cross-platform voice cloning API: cloning(), clone_from(), and start_cloning() / VoiceClone for file, PCM, or live microphone capture, aligned across Python, JavaScript, Swift, and Java.
AgentFlow and voice-cloning examples on Android and iOS/Swift, plus dictation and meeting note taker web examples.
Language tabs on the web example code snippets.
Hugging Face mirror of every downloadable asset at moonshine-ai/moonshine-voice-assets.

Breaking: DialogFlow is renamed to AgentFlow everywhere (APIs, packages, and example apps).
Breaking: High-level client APIs are regularized across Python, JavaScript, Swift, and Java around construct → configure with chainable setters → load(). In particular, Python MicTranscriber and TextToSpeech no longer download and open models inside the constructor.
Breaking: The C++ binding (moonshine-cpp.h) follows the same higher-level shape for transcription and TTS.
Breaking: Only OnnxRuntime flatbuffer models (.ort) are accepted. Supplying .onnx (or ONNX external-data sidecars) fails with a clear migration error. Convert with python scripts/convert-models-to-ort.py. See docs/ort-only-models.md.
Breaking: Speaker-diarization models are no longer embedded in the library. With identify_speakers, they download on first use like other models (~8 MB off every mobile binary; Android arm64 install ~24.6 MB → ~16.4 MB, iOS linked binary ~30.6 MB → ~22.4 MB). See docs/diarization-models.md.
Downloadable assets are served from download.moonshine.ai (and the Hugging Face mirror) instead of the old GCP-hosted buckets; large model blobs are no longer kept in git LFS in this repo.
Smaller WebAssembly downloads after ORT-only packaging and cleanup of unused model files.
Improved quantization accuracy for shipped models.
Streaming transcription backs off the inference interval when it falls behind realtime, to reduce piled-up work.

Remaining public references to the old Intent API (use AgentFlow phrase matching instead).
Embedded diarization model payloads from the core library binary.
