Getting Started with Neural TTS: Technical Quickstart Guides

Implementing Neural TTS in Python: A Step-by-Step Guide

Python remains one of the most versatile programming languages and is renowned for its ease of use in building applications — including those for Neural TTS. A starting point for implementing neural TTS is using the Azure Cognitive Services Speech SDK. The following snippet demonstrates how you can convert text to speech in Python using this SDK.

Below is a basic example of how to use the Azure Cognitive Services Speech SDK with Python to make a simple Text-to-Speech request:

import azure.cognitiveservices.speech as speechsdk

Set up the subscription info for the Azure Speech Service:

subscription_key = "YourSubscriptionKey"
service_region = "YourServiceRegion"

Set up the speech configuration using the subscription info:

speech_config = speechsdk.SpeechConfig(subscription=subscription_key, region=service_region)

Enable neural voice, this is optional and depends on availability in the region:

speech_config.speech_synthesis_voice_name = "en-US-JessaNeural"

Create a speech synthesizer with the given settings:

speech_synthesizer = speechsdk.SpeechSynthesizer(speech_config=speech_config)

Get a text from the user to synthesize:

text_to_synthesize = input("Enter some text that you want to synthesize: ")

Synthesize the text:

result = speech_synthesizer.speak_text_async(text_to_synthesize).get()

Check the result:

if result.reason == speechsdk.ResultReason.SynthesizingAudioCompleted:
print("Speech synthesized for the text: "{}"".format(text_to_synthesize))
elif result.reason == speechsdk.ResultReason.Canceled:
cancellation_details = result.cancellation_details
print("Speech synthesis canceled: {}".format(cancellation_details.reason))
if cancellation_details.reason == speechsdk.CancellationReason.Error:
print("Error details: {}".format(cancellation_details.error_details))

This code will prompt the user for text input and synthesize speech from the text using Azure's neural TTS service. It is also set up to handle errors that may occur during the process. Remember, the subscription key and service region must be replaced with your actual Azure subscription details.

Integrating Neural TTS with Java and JavaScript: Code Samples

Java and JavaScript are potent technologies that can also leverage Azure Cognitive Services for Neural TTS integration. Here’s a basic guide to help you get started with incorporating neural TTS into your Java or JavaScript applications.

For Java applications, the following example shows how to synthesize speech using the Azure Speech SDK for Java:

const axios = require('axios');
const fs = require('fs');

const headers = {
    'Authorization': 'Bearer YOUR_API_KEY',

const data = {
    'Text': '<YOUR_TEXT>', // Up to 1,000 characters
    'VoiceId': '<VOICE_ID>', // Scarlett, Dan, Liv, Will, Amy
    'Bitrate': '192k', // 320k, 256k, 192k, ...
    'Speed': '0', // -1.0 to 1.0
    'Pitch': '1', // 0.5 to 1.5
    'Codec': 'libmp3lame', // libmp3lame or pcm_mulaw

    method: 'post',
    url: '',
    headers: headers,
    data: data,
    responseType: 'stream'
}).then(function (response) {'audio.mp3'))

For JavaScript applications that run in the browser, you might use the Web Speech API for implementing TTS functionalities. This API is native to modern browsers and does not require an Azure subscription. Here's a simple example of how you can use it:

const synth = window.speechSynthesis;
const inputForm = document.querySelector('form');
const inputTxt = document.querySelector('input');

inputForm.onsubmit = function(event) {

const utterThis = new SpeechSynthesisUtterance(inputTxt.value);

Remember to check compatibility since the Web Speech API may not be supported in all browsers or may have different levels of support for various languages and voices, including neural ones.
