Aristech TTS-Client for Rust

This is the Rust client implementation for the Aristech TTS-Server.

Installation

To use the client in your project, add it to your Cargo.toml or use cargo to add it:

cargo add aristech-tts-client

Usage

use aristech_tts_client::{get_client, synthesize, SpeechRequest, SpeechRequestOption, TlsOptions};
use std::error::Error;

#[tokio::main]
async fn main() -> Result<(), Box<dyn Error>> {
    let client = get_client(
        "https://tts.example.com",
        Some(TlsOptions::default()),
    ).await?;

    let request = SpeechRequest {
        text: "Text to speak.".to_string(),
        options: Some(SpeechRequestOption {
            voice_id: "anne_en_GB".to_string(),
          ..SpeechRequestOption::default()
        }),
        ..SpeechRequest::default()
    };
    let data = synthesize(&mut client, request).await?;
    std::fs::write("output.wav", data).expect("Unable to write file");

    Ok(())
}

There are several examples in the examples directory:

• file.rs: Demonstrates how convert text to speech and save the audio to a file.
• streaming.rs: Demonstrates how to stream audio to a sox process which plays the audio as it is being streamed.
• voices.rs: Demonstrates how to get the available voices from the server.
• phoneset.rs: Demonstrates how to retrieve the phoneset for a voice.
• transcribe.rs: Demonstrates how to retrieve the pronunciation of a word for a voice.

You can run the examples directly using cargo like this:

1. Create a .env file in the rust directory:

HOST=tts.example.com
# The credentials are optional but probably required for most servers:
TOKEN=your-token
SECRET=your-secret

# The following are optional:
# ROOT_CERT=your-root-cert.pem # If the server uses a self-signed certificate
# If neither credentials nor an explicit root certificate are provided,
# you can still enable SSL by setting the SSL environment variable to true:
# SSL=true
# VOICE_ID=some-available-voice-id

2. Run the examples, e.g.:

cargo run --example file

Build

To build the library, run:

cargo build
