• Whisper — Whisper is a general-purpose automatic speech recognition (ASR) model developed by OpenAI. Whisper can be used to transcribe audio into whatever language the audio is in or to translate and transcribe the audio into English.

What is a text to speech voice generator API?

The latest addition to OpenAI's arsenal is the text to speech voice generator API. A text to speech (TTS) voice generator API is a software interface that enables developers to integrate text to speech or AI voice functionality into their applications, websites, or services. This API allows users to convert written text into spoken words by leveraging advanced machine learning algorithms and speech synthesis technology. Developers can send text strings to the API, which then processes the input and generates corresponding audio output in the form of a natural-sounding human voice.

How OpenAI voice generator API works

The OpenAI voice generator API enables developers to integrate up to six different AI-generated synthetic voices into their applications, creating a seamless and engaging experience for users. Developers can implement this API by creating a speech endpoint with the model name, the text that needs to be transformed into an audio file, and the voice they wish to use. For example, a simple request could be:

from pathlib import Path
from openai import OpenAI
client = OpenAI()

speech_file_path = Path(__file__).parent / "speech.mp3"
response = client.audio.speech.create(
  model="tts-1",
  voice="alloy",
  input="Today is a wonderful day to build something people love!"
)

response.stream_to_file(speech_file_path)
