-v, --voice The voice to be used
[string] [default: "zh-CN-XiaoyiNeural"]
-l, --lang The language to be used [string] [default: "zh-CN"]
-o, --outputFormat The output format

-p, --proxy example: http://localhost:7890 [string]
Examples:
npx node-edge-tts -t 'Hello world' -f './output.mp3'
const { EdgeTTS } = require('node-edge-tts')
or
import { EdgeTTS } from 'node-edge-tts'
const tts = new EdgeTTS()
await tts.ttsPromise('Hello world', path_to_audiofile_with_extension)
const tts = new EdgeTTS({
voice: 'en-US-AriaNeural',
lang: 'en-US',
outputFormat: 'audio-24khz-96kbitrate-mono-mp3',
saveSubtitles: true,
proxy: 'http://localhost:7890',
})
You can find the available options for speechconfig at voice/lang|outputFormat, but not all options are accessible due to limitations of the services provided by Microsoft Edge.
Subtitles are json files with the same name as the audio file, as shown below:
\\ the *start* is the time point at which the *part* begins,
\\ the *end* is the time point at which the *part* ends,
\\ measured in milliseconds.
