OpenAI FM Technical Insights
Expert answers about our free TTS AI
OpenAI FM utilizes advanced transformer-based models, which are a type of neural network architecture particularly effective for sequence-to-sequence tasks like text-to-speech. These models are combined with sophisticated waveform synthesis techniques to generate highly natural and human-like speech. All these cutting-edge technologies are offered completely free of charge.
For optimal performance and to ensure high-quality synthesis, OpenAI FM supports text inputs up to 5,000 characters per request. This allows for processing substantial amounts of text while maintaining efficiency. You are free to process as many inputs as you need within this limit.
Our AI models are rigorously evaluated using industry-standard metrics, achieving an impressive 95% naturalness score on Mean Opinion Score (MOS) benchmarks. This indicates that the synthesized voices are perceived as very close to human speech quality. This high level of quality is consistently provided for free.
We prioritize your data privacy and security. All text and audio data processed by OpenAI FM undergoes end-to-end encryption to protect your information. Furthermore, all processed data is automatically deleted from our servers within 15 minutes of synthesis, ensuring your content remains confidential. This secure service is entirely free.
