MsEdgeTTS

An Azure Speech Service module that uses the Microsoft Edge Read Aloud API.

Full support for SSML, however, the following is the default SSML object:

<speak version="1.0" xmlns="http://www.w3.org/2001/10/synthesis" xmlns:mstts="https://www.w3.org/2001/mstts"
       xml:lang="${this._voiceLang}">
    <voice name="${voiceName}">
        ${input}
    </voice>
</speak>

Documentation on the SSML format can be found here . All supported audio formats can be found here.

Example usage

Write to Stream

import {MsEdgeTTS} from "msedge-tts";

const tts = new MsEdgeTTS();
await tts.setMetadata("en-IE-ConnorNeural", MsEdgeTTS.OUTPUT_FORMATS.WEBM_24KHZ_16BIT_MONO_OPUS);
const readable = tts.toStream("Hi, how are you?");

readable.on("data", (data) => {
    console.log("DATA RECEIVED", data);
    // raw audio file data
});

readable.on("closed", () => {
    console.log("STREAM CLOSED");
});

Write to File

import {MsEdgeTTS} from "msedge-tts";

(async () => {
    const tts = new MsEdgeTTS();
    await tts.setMetadata("en-US-AriaNeural", MsEdgeTTS.OUTPUT_FORMATS.WEBM_24KHZ_16BIT_MONO_OPUS);
    const filePath = await tts.toFile("./example_audio.webm", "Hi, how are you?");  
})
