Example usage

Install Whisper 1.5.5 (the latest version at the time of writing that we find works well and supports token-level timestamps) and the medium.en model to the whisper.cpp folder.

install-whisper.cpp
tsx
import path from "path";
import {
  downloadWhisperModel,
  installWhisperCpp,
  transcribe,
  convertToCaptions,
} from "@remotion/install-whisper-cpp";
 
const to = path.join(process.cwd(), "whisper.cpp");
 
await installWhisperCpp({
  to,
  version: "1.5.5",
});
 
await downloadWhisperModel({
  model: "medium.en",
  folder: to,
});
 
const { transcription } = await transcribe({
  model: "medium.en",
  whisperPath: to,
  inputPath: "/path/to/audio.wav",
  tokenLevelTimestamps: true,
});
 
for (const token of transcription) {
  console.log(token.timestamps.from, token.timestamps.to, token.text);
}
 
// Optional: Apply our recommended postprocessing
const { captions } = convertToCaptions({
  transcription,
  combineTokensWithinMilliseconds: 200,
});
 
for (const line of captions) {
  console.log(line.text, line.startInSeconds);
}
