TTS-1

TTS-1 API Overview

TTS-1 (Text-To-Speech) is an advanced neural network model developed by OpenAI designed to convert written text into natural and compelling speech. It leverages state-of-the-art deep learning techniques in natural language processing (NLP) to synthesize voice output that closely mimics human speech patterns and intonation.

Technical Specifications

• Model Type: Deep learning-based TTS neural network
• Input: Text prompt including punctuation
• Output: High-fidelity audio waveform
• Core Technology: NLP-driven acoustic feature prediction combined with neural vocoders
• Deployment: Cloud or edge deployment compatible

Performance Benchmarks

• High Mean Opinion Score (MOS) in subjective listening tests, indicating user preference over traditional TTS systems
• Lower latency compared to earlier TTS architectures, enabling near real-time speech synthesis
• Competitive word error rates (WER) when synthesized speech is used with speech recognition systems

Key Features

• Natural-sounding speech with human-like intonation and rhythm
• Context-aware speech synthesis capturing appropriate emotional tones
• End-to-end pipeline from text analysis to audio output
• Robust handling of varying sentence structures and punctuation
• Scalable for different voice types and speaking styles

TTS-1 API Pricing

• $15.75 / 1M tokens
