# Transcription DevTools
|
||
|
|
|
||
|
|
Includes:
|
||
|
|
* __JiWER__ CLI NodeJS wrapper
|
||
|
|
* Benchmark tool to test multiple transcription engines
|
||
|
|
* TypeScript classes to evaluate word-error-rate of files generated by the transcription
|
||
|
|
|
||
|
|
## Build
|
||
|
|
|
||
|
|
```sh
|
||
|
|
npm run build
|
||
|
|
```
|
||
|
|
|
||
|
|
## Benchmark
|
||
|
|
|
||
|
|
A benchmark of available __transcribers__ might be run with:
|
||
|
|
```sh
|
||
|
|
npm run benchmark
|
||
|
|
```
|
||
|
|
```
|
||
|
|
┌────────────────────────┬───────────────────────┬───────────────────────┬──────────┬────────┬───────────────────────┐
|
||
|
|
│ (index) │ WER │ CER │ duration │ model │ engine │
|
||
|
|
├────────────────────────┼───────────────────────┼───────────────────────┼──────────┼────────┼───────────────────────┤
|
||
|
|
│ 5yZGBYqojXe7nuhq1TuHvz │ '28.39506172839506%' │ '9.62457337883959%' │ '41s' │ 'tiny' │ 'openai-whisper' │
|
||
|
|
│ x6qREJ2AkTU4e5YmvfivQN │ '29.75206611570248%' │ '10.46195652173913%' │ '15s' │ 'tiny' │ 'whisper-ctranslate2' │
|
||
|
|
└────────────────────────┴───────────────────────┴───────────────────────┴──────────┴────────┴───────────────────────┘
|
||
|
|
```
|
||
|
|
|
||
|
|
The benchmark may be run with multiple model builtin sizes:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
MODELS=tiny,small,large npm run benchmark
|
||
|
|
```
|
||
|
|
|
||
|
|
## Jiwer
|
||
|
|
|
||
|
|
> *JiWER is a python tool for computing the word-error-rate of ASR systems.*
|
||
|
|
> https://jitsi.github.io/jiwer/cli/
|
||
|
|
|
||
|
|
__JiWER__ serves as a reference implementation to calculate errors rates between 2 text files:
|
||
|
|
- WER (Word Error Rate)
|
||
|
|
- CER (Character Error Rate)
|
||
|
|
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
```typescript
|
||
|
|
const jiwerCLI = new JiwerClI('./reference.txt', './hypothesis.txt')
|
||
|
|
|
||
|
|
// WER as a percentage, ex: 0.03 -> 3%
|
||
|
|
console.log(await jiwerCLI.wer())
|
||
|
|
|
||
|
|
// CER as a percentage: 0.01 -> 1%
|
||
|
|
console.log(await jiwerCLI.cer())
|
||
|
|
|
||
|
|
// Detailed comparison report
|
||
|
|
console.log(await jiwerCLI.alignment())
|
||
|
|
```
|
||
