A little curiosity. A world of open source.
THE FIRST COLLECTIONBatchalign3 is a TalkBank audio and ML pipeline for producing and enriching CHAT transcripts, covering ASR, forced alignment, neural morphotagging, translation and utterance segmentation. It ships a CLI, Python package, PyO3 bridge, React dashboard and an experimental Tauri desktop shell.
SpeechRecognition is a Python library for speech recognition supporting multiple engines and APIs, both online and offline, including CMU Sphinx, Google, Azure, IBM, Vosk, Whisper, and OpenAI.
Mimora is a free, fully local pronunciation trainer for English and Spanish. It uses on-device TTS, speech recognition, and a local LLM to generate phrases and score user attempts with word-level feedback, requiring no cloud or API keys.
A high-performance C/C++ implementation for inference of OpenAI's Whisper automatic speech recognition (ASR) model, designed for lightweight and cross-platform deployment.
Premove ITN is an open-source, context-aware inverse text normalization tool for English voice-agent transcripts. It converts spoken ASR output into canonical written forms using a generate-score-decode pipeline with DeBERTa contextual scoring.
A fast reimplementation of OpenAI's Whisper model using CTranslate2, offering improved transcription speed and reduced memory usage.
Hugging Face Transformers is a model-definition framework for machine learning across text, vision, audio, and multimodal tasks. It provides a unified API for inference and training with over 1 million pretrained checkpoints.
SenseVoiceSmall is an open-source speech foundation model for ASR, language ID, emotion recognition and audio event detection, covering Mandarin, Cantonese, English, Japanese and Korean with fast non-autoregressive inference.
ESPnet is an end-to-end speech processing toolkit built on PyTorch, covering ASR, TTS, speech translation, enhancement, diarization, and more, with reproducible recipes and pretrained models.
WhisperLiveKit is a self-hosted, ultra-low-latency speech-to-text pipeline. It provides real-time transcription, speaker diarization, and translation via WebSocket and OpenAI/Deepgram-compatible APIs.
