TTS Programming Tutorials

Integrating TTS APIs

Integrating Text-to-Speech (TTS) APIs into software applications allows developers to create more interactive and accessible products. For example, using Google's Cloud Text-to-Speech API with Python involves a few straightforward steps. After setting up your Google Cloud Platform account and retrieving your API key, you install the necessary client library and then use the following code to convert text into speech:

import requests

response = requests.post(
  'https://api.v6.unrealspeech.com/stream',
  headers = {
    'Authorization' : 'Bearer YOUR_API_KEY'
  },
  json = {
    '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
  }
)

with open('audio.mp3', 'wb') as f:
    f.write(response.content)

This code will produce an MP3 file from the input text using the desired voice and language settings.

Customizing TTS Voices and Languages

Customizing voices and languages with a TTS API involves specifying additional parameters to adjust voice characteristics such as pitch, speaking rate, and volume. For instance, AWS's Polly service offers such customization, and here is how you might use it with Python's boto3 library:

import boto3

# Create a Polly client
polly = boto3.client('polly')

# Request speech synthesis
response = polly.synthesize_speech(Text='Your text here', OutputFormat='mp3', VoiceId='Joanna',
SpeechMarkTypes=['ssml'],
LanguageCode='en-US',
Engine='neural',
SampleRate='22050',
TextType='ssml')

# Access the audio stream from the response
if 'AudioStream' in response:
with open('speech.mp3', 'wb') as file:
file.write(response['AudioStream'].read())
print('File "speech.mp3" has been written')

In the above Python script, various parameters of the Polly service are set to tailor the resultant speech to specific requirements. Remember, the specifics of such customization will vary across different TTS services and APIs.
