Guia de instalação completo
// como funciona

Como funciona

  1. Install WhisperX

    The simple route from the README: pip install whisperx (install the CUDA toolkit first if you want GPU acceleration; CPU works without it).

  2. Transcribe a file

    Run whisperx on an audio or video file — it transcribes, aligns word-level timestamps and (with diarization enabled and a Hugging Face token) labels speakers.

  3. Use the timestamps

    Take the JSON/SRT/VTT output into your subtitle, clipping or editing pipeline — word timings and speaker turns are already in the file.

Por que as pessoas gostam tanto

Word-level timestamps

Forced phoneme alignment turns Whisper segments into accurate per-word timings — the feature plain Whisper lacks.

Speaker diarization

Who said what, labelled per segment, alongside the transcript.

70x realtime batching

VAD-based batched inference on faster-whisper makes long recordings cheap to process on a GPU.

Pipeline-ready outputs

JSON, SRT, VTT and other subtitle formats that clipping and editing tools consume directly.

Execute você mesmo

  1. Install from PyPI

    The README recommended route.

    pip install whisperx
  2. Speed up alignment (optional)

    The README fast extra: Numba JIT for the alignment loops on long files.

    pip install "whisperx[fast]"
  3. Transcribe

    Basic CLI use; add --diarize and alignment options per the README for the full pipeline.

O que você pode criar

Transcription feeds two smaller projects on this shelf: AI Clipping Generator packages an AI clipping business as a production-ready Next.js SaaS boilerplate, and Second Brain keeps the results in a fully local, private, self-hostable knowledge base. Readers working through the Clipping shelf also stop at maxhub-api-skills, Agent skills that pull data from 21 social platforms into your AI workflow.

// perguntas frequentes

Perguntas frequentes

Who makes WhisperX?

Max Bain (m-bain/whisperX on GitHub); the underlying ASR is OpenAI Whisper via faster-whisper, with wav2vec2 alignment models.

Is WhisperX free?

Yes — BSD-2-Clause licensed. Diarization models from Hugging Face may ask you to accept their terms and use a token, per the README.

How is it different from plain Whisper?

Whisper gives you segment-level text. WhisperX adds accurate word-level timestamps via forced alignment, speaker diarization, and much faster batched inference — the three things production pipelines actually need.

How does it compare to a well-known alternative?

Against faster-whisper alone, WhisperX is the full pipeline (alignment + diarization) rather than just the fast ASR engine — it is built on faster-whisper. Against hosted transcription APIs, it runs locally and free, at the cost of your own GPU time.

How do I get started?

pip install whisperx, then whisperx yourfile.mp3 --model large-v2. Add --diarize once you have a Hugging Face token configured.
