whisper-medium.en_timestamped#

This is the ONNX version of openai/whisper-medium.en with word-level timestamp support for use with Transformers.js.

Features#

  • ✅ Word-level timestamps via cross-attention (alignment_heads configured)
  • ✅ Multiple quantization variants (fp32, int8, uint8)
  • ✅ Compatible with Transformers.js for browser-based inference
  • ✅ Merged decoder model for efficient inference

Usage with Transformers.js#

import { pipeline } from '@huggingface/transformers';

const transcriber = await pipeline(
  'automatic-speech-recognition',
  'neonwatty/whisper-medium.en_timestamped'
);

const result = await transcriber(audioUrl, {
  return_timestamps: 'word',
  chunk_length_s: 30,
  stride_length_s: 5,
});

console.log(result);
// { text: "Hello world", chunks: [{ text: "Hello", timestamp: [0.0, 0.5] }, ...] }

Model Files#

The model includes the following ONNX files in the onnx/ directory:

FileDescription
encoder_model.onnxAudio encoder (fp32)
decoder_model.onnxText decoder (fp32)
decoder_with_past_model.onnxDecoder with KV cache
decoder_model_merged.onnxMerged decoder for efficient inference
*_int8.onnxINT8 quantized versions
*_uint8.onnxUINT8 quantized versions
