Update realtimestt requirement from <0.4,>=0.3.7 to >=0.3.7,<1.1

[dependabot]

Updates the requirements on realtimestt to permit the latest version.

Release notes

Sourced from realtimestt's releases.

v1.0.0

RealtimeSTT v1.0.0

Major Features

• New Transcription Engine System

  • Added a lazy-loaded engine abstraction under RealtimeSTT/transcription_engines.
  • faster_whisper remains the compatibility default.
  • Final and realtime transcription can now use different backends via transcription_engine and realtime_transcription_engine.
  • Backend-specific settings can be passed separately with transcription_engine_options and realtime_transcription_engine_options.

• New ASR Engines

  • Added whisper_cpp through pywhispercpp.
  • Added openai_whisper for OpenAI’s local Whisper package.
  • Added Moonshine, NVIDIA Parakeet/NeMo, Granite Speech, Qwen3-ASR, and Cohere Transcribe adapters.
  • Added CPU INT8 sherpa-onnx paths for Parakeet and Moonshine.
  • Added optional Kroko-ONNX aliases: kroko_onnx, kroko, and banafo_kroko.

• FastAPI Browser Streaming Server

  • Added example_fastapi_server, a browser-based streaming STT server with binary WebSocket audio input.
  • Added multi-user support with session-local audio buffers, VAD state, transcript state, segment IDs, clear/reset, warnings, errors, realtime text, and final text.
  • Heavy ASR models are shared through final/realtime inference lanes instead of loading one model per browser session.
  • Added fair per-session scheduling, realtime coalescing, stale realtime job dropping, final-job preservation, capacity limits, /health, /api/config, and /api/metrics.
  • Added wake-word support in the FastAPI server, including Porcupine/OpenWakeWord options and a follow-up window after wake activation.

• Syllable-Boundary Realtime Scheduling

  • Added optional CPU-only acoustic boundary scheduling with realtime_transcription_use_syllable_boundaries.
  • The scheduler triggers realtime ASR near likely syllable/vowel boundaries, with configurable sensitivity and follow-up delays.
  • In the reference fixture, realtime ASR calls dropped from 239 to 44, an 81.6% reduction, while final WER stayed at 0.000.

Improvements

• Customizable Installation

  • pip install RealtimeSTT now installs the core recorder, audio, WebRTC VAD, and Silero VAD dependencies.
  • Optional ASR and wake-word stacks are exposed as extras, including faster-whisper, whisper-cpp, openai-whisper, sherpa-onnx, parakeet, qwen, porcupine, openwakeword, wakewords, recommended, and all.
  • Wake-word dependencies are no longer mandatory unless selected. WebRTC VAD and Silero VAD remain core dependencies because the recorder still initializes both VAD paths.

• Realtime Text Stability

  • Added a structured RealtimeTextStabilizer with stable deltas, unstable preview text, outlier handling, finalization checks, and diagnostics.
  • Added on_realtime_text_stabilization_update for applications that need structured realtime stabilization events.

• Docs And Examples

  • Reworked the README into a shorter entry point and moved detailed guidance into docs/.
  • Added docs for installation, configuration, transcription engines, wake words, external audio, FastAPI server usage, troubleshooting, testing, and architecture.
  • Added per-engine documentation for faster-whisper, whisper.cpp, OpenAI Whisper, Moonshine, sherpa-onnx, Parakeet/NeMo, Transformers engines, Cohere, and Kroko-ONNX.

Fixes

• Recorder Stability: Slow Final Transcription
  • Fixed a recorder bug where slow CPU final transcription could cause following speech to be missed while text() was blocked.
