3. faster-whisper

   2 28 23,557 6.8 Python

   Faster Whisper transcription with CTranslate2

   

   Project mention: I built a free, local video transcription tool, because I didn't want to pay $10/hour or upload my files to a stranger's server | dev.to | 2026-05-09

   WhisperX: Automatic Speech Recognition with Word-level Timestamps (& Diarization)

   

   Project mention: The Unit Economics of Speech-to-Text Just Collapsed | dev.to | 2026-04-18

   Look at what arrived between mid-2023 and mid-2025. Gandhi et al.'s Distil-Whisper (2023) distilled large-v2 into a 756M-param student that runs 6× faster with a 1% WER gap on out-of-distribution audio, using large-scale pseudo-labelling. Georgi Gerganov's whisper.cpp made CPU-only and mobile inference a default rather than a party trick; a base.en checkpoint transcribes real-time on an M1 without touching a GPU. Max Bain's WhisperX added forced-alignment and diarization on top, so word-level timestamps and speaker labels stopped being a premium-tier differentiator.

5. FunASR

15. ml-road

    14 1 4,825 3.6 Python

    Machine Learning and Agentic AI Resources, Practice and Research

    

    Project mention: Neural Networks: Zero to Hero | news.ycombinator.com | 2026-01-04

    Well, no ... For a start any "AI" course 20 years ago probably wouldn't have even mentioned neural nets, and certainly not as a mainstream technique.

    A 20yr old "AI" curriculum would have looked more like the 3rd edition of Russel & Norvig's "Artificial Intelligence - A Modern Approach".

    https://github.com/yanshengjia/ml-road/blob/master/resources...

    Karpathy's videos aren't an AI (except in modern sense of AI=LLMs) course, or even a machine learning course, or even a neural network course for that matter (despite the title) - it's really just "From Zero to LLMs".

16. distil-whisper

    15 10 4,065 7.6 Python

    Distilled variant of Whisper for speech recognition. 6x faster, 50% smaller, within 1% word error rate.

    

17. whisper-asr-webservice

    16 12 3,281 8.1 Python

    OpenAI Whisper ASR Webservice API

    

    Project mention: How GPU-Powered Coding Agents Can Assist in Development of GPU-Accelerated Software | dev.to | 2026-02-28

    Imagine owning a massive Plex media library with hundreds of foreign-language films and TV shows. You want subtitles for everything, but manually sourcing them is a nightmare — mismatched timings, missing translations, incomplete coverage. Tools like Bazarr exist specifically to automate subtitle management for Plex and Sonarr/Radarr libraries, and they ship with built-in integration for whisper-asr-webservice — a self-hosted REST API that wraps OpenAI's Whisper speech recognition model. Point Bazarr at a whisper-asr-webservice endpoint, and it will automatically transcribe and generate subtitles for every piece of media in your library, in any language Whisper supports.

18. whisper-standalone-win

    17 8 3,080 5.0 Python

    Whisper & Faster-Whisper standalone executables for those who don't want to bother with Python.

    

    Project mention: Why removing 'um' from a recording is harder than it sounds | news.ycombinator.com | 2026-06-12

    Yeah, that's in faster-whisper-xxl via the --diarize parameter with additional options to tweak how it works:

    https://github.com/Purfview/whisper-standalone-win/discussio...

    I haven't used it when subtitling, though, so I don't know much more.

19. lingvo

    18 1 2,864 5.5 Python

    Lingvo

    

20. whisper-timestamped

    19 3 2,818 6.1 Python

    Multilingual Automatic Speech Recognition with word-level timestamps and confidence

    

    Project mention: Cohere Transcribe: Speech Recognition | news.ycombinator.com | 2026-03-31

    There is also: https://github.com/linto-ai/whisper-timestamped

    It doesn't use an extra model (so it supports every language that works with Whisper out of the box and use less memory), it works by applying Dynamic Time Warping to cross-attention weights.

21. lip-reading-deeplearning

    20 1 1,903 10.0 Python
