Text-to-Speech (TTS) Project - An OpenAI Audio API project converting text into natural-sounding speech using GPT-4o mini TTS model.

## Core Technology of OpenAI TTS The project is powered by the **GPT-4o mini TTS model**, part of OpenAI's Audio API. It converts text into natural-sounding speech with features like emotional range adjustment and multilingual support. ## Built-in Voices in OpenAI TTS The project provides **11 built-in voices** (e.g., `alloy`, `nova`, `echo`), optimized for English. Demo samples are available on [OpenAI's demo page](https://openai.fm). ## Language Support in OpenAI TTS It supports **~40 languages**, including Chinese, English, Arabic, and Afrikaans, based on Whisper model's language list ([Whisper Languages](https://github.com/openai/whisper#available-models-and-languages)). ## Output Formats in OpenAI TTS Supported formats include **MP3 (default)**, Opus, AAC, FLAC, WAV, and PCM, catering to diverse use cases. ## Use Cases of OpenAI TTS Key applications include: - **Education**: Converting blog posts or lectures into audio. - **Customer Service**: Real-time voice interactions (e.g., AI assistants). - **Multilingual Content**: Generating audio in multiple languages. ## Model Options in OpenAI TTS Users can choose between: - **gpt-4o-mini-tts**: Balanced for real-time applications. - **tts-1**: Lower latency but reduced quality. - **tts-1-hd**: Higher quality with increased latency. ## Custom Voice Support in OpenAI TTS **No**, the project does not support custom voice creation. Users must select from the 11 built-in voices. ## Compliance Requirements for OpenAI TTS Users **must disclose** that the audio is AI-generated, as per [OpenAI's Usage Policies](https://openai.com/policies/usage-policies). Ownership of generated audio belongs to the creator. ## Real-Time Streaming in OpenAI TTS It uses **chunked transfer encoding** to stream audio dynamically, ideal for interactive scenarios like live customer support. ## Technical Documentation for OpenAI TTS Full documentation is available at [OpenAI's TTS Guide](https://platform.openai.com/docs/guides/text-to-speech), including API references and integration examples. ### Citation sources: - [Text-to-Speech (TTS) Project](https://platform.openai.com/docs/guides/text-to-speech) - Official URL Updated: 2025-04-01
