# audio-testing |
|
|
|
|
|
## Overview |
|
|
|
|
|
This is a small, open dataset designed for quick validation of audio-related pipelines and applications, especially for **Text-to-Speech (TTS)** and **Speech-to-Text (STT)** systems. |
|
|
It provides a few short, diverse audio clips and corresponding text transcripts, allowing developers to verify input/output handling, audio processing, and transcription logic without downloading large datasets. |
|
|
|
|
|
## Contents |
|
|
|
|
|
* 3 short audio samples (`.mp3`, `.wav`) |
|
|
* `metadata.jsonl` file containing text transcripts and file references |
|
|
|
|
|
| Field | Type | Description | |
|
|
| ------- | ---------- | ----------------------- | |
|
|
| `audio` | audio file | Raw audio data | |
|
|
| `text` | string | Transcript of the audio | |
|
|
|
|
|
## Example Usage |
|
|
|
|
|
```typescript |
|
|
async function fetchAudio(url: string): Promise<{ |
|
|
data: Buffer; |
|
|
mimeType: string; |
|
|
}> { |
|
|
const response = await fetch(url); |
|
|
if (!response.ok) { |
|
|
throw new Error(`Failed to fetch audio: ${response.statusText}`); |
|
|
} |
|
|
const arrayBuffer = await response.arrayBuffer(); |
|
|
const data = Buffer.from(arrayBuffer); |
|
|
const mimeType = response.headers.get("content-type") || "audio/wav"; |
|
|
return { data, mimeType }; |
|
|
} |
|
|
|
|
|
const audioUrl = "https://huggingface.co/datasets/JacobLinCool/audio-testing/resolve/main/audio/audio-1.mp3"; |
|
|
const { data, mimeType } = await fetchAudio(audioUrl); |
|
|
const transcription = await transcribe(data, mimeType); |
|
|
const words = "this is a test audio generated by the model".split(" "); |
|
|
// pass if WER < 10% |
|
|
let matchCount = 0; |
|
|
for (const word of words) { |
|
|
if (transcription.includes(word)) { |
|
|
matchCount++; |
|
|
} |
|
|
} |
|
|
expect(matchCount / words.length).toBeGreaterThan(0.9); |
|
|
``` |
|
|
|
|
|
Ideal for verifying: |
|
|
|
|
|
* TTS model output alignment with ground-truth text |
|
|
* STT transcription accuracy and error handling |
|
|
* Audio I/O integration in pipelines or apps |
