Edge TTS

Edge TTS is a powerful Text-to-Speech (TTS) package that leverages Microsoft's Edge capabilities. This package allows you to synthesize speech from text and manage voice options easily through a command-line interface (CLI).

Features

• Text-to-Speech: Convert text into natural-sounding speech using Microsoft Edge's TTS capabilities.
• Multiple Voices: Access a variety of voices to suit your project's needs.
• Audio Export Options: Export synthesized audio in different formats (raw, base64, or directly to a file).
• Command-Line Interface: Use a simple CLI for easy access to functionality.
• Easy Integration: Modular structure allows for easy inclusion in existing projects.

Installation

You can install Edge TTS via npm. Run the following command in your terminal:

bun add @andresaya/edge-tts

npm install @andresaya/edge-tts

Usage

Command-Line Interface

You can install Edge TTS via npm. bun Run the following command in your terminal:

npm install -g @andresaya/edge-tts

bun install --global edge-tts

To synthesize speech from text, use the following command:

edge-tts synthesize -t "Hello, world!" -o hello_world_audio

To list available voices, run:

edge-tts voice-list

Integration into Your Project To use Edge TTS in your Bun project, you can import it like this:

import { EdgeTTS } from '@andresaya/edge-tts';

// Initialize the EdgeTTS service
const tts = new EdgeTTS();

// Get voices
const voices = await tts.getVoices();  
console.log(voices);  // Display available voices

// Synthesize text with options for voice, rate, volume, and pitch
await tts.synthesize("Hello, world!", 'en-US-AriaNeural', {
    rate: '0%',       // Speech rate (range: -100% to 100%)
    volume: '0%',     // Speech volume (range: -100% to 100%)
    pitch: '0Hz'      // Voice pitch (range: -100Hz to 100Hz)
});

// Export synthesized audio in different formats
tts.toBase64();   // Get audio as base64
await tts.toFile("output_audio");       // Save audio to file
await tts.toRaw();         // Get raw audio buffer

Export Options

After synthesizing speech, you can export the audio in various formats:

• toBase64: Returns the audio as a Base64 string.
• toFile: Saves the audio to a specified file (e.g., "output.wav").
• toRaw: Returns the raw audio stream.
