MsEdgeTTS

msedge-tts-browserify clone from Migushthe2nd/MsEdgeTTS, which based on nodejs. To better use it on browser, I rewrite some codes--remove node stream, fs and crypto, replace axios with fetch. This repo only support browser but nodejs.

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

~~Full support for SSML~~ Only supports speak, voice, and prosody element types. 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}">
        <prosody rate="${rate}" pitch="${pitch}" volume="${volume}">
            ${input}
        </prosody>
    </voice>
</speak>

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

Example usage

Make sure to escape/sanitize your user's input! Use a library like xml-escape.

Write to stream

import { MsEdgeTTS, OUTPUT_FORMAT } from "msedge-tts";

const tts = new MsEdgeTTS();
await tts.setMetadata("en-IE-ConnorNeural", OUTPUT_FORMAT.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("close", () => {
    console.log("STREAM CLOSED");
});

API

This library only supports promises.
