At OpenAI DevDay on November 6th 2023, OpenAI announced a new text-to-speech (TTS) model that offers 6 preset voices to choose from, in their standard format as well as their respective high-definition (HD) equivalents. Today, we are excited to announce that we are bringing those models in preview to Azure. Developers can now access OpenAI’s TTS voices through Azure OpenAI and Azure AI Speech services. Each of the 6 voices has its own personality and style. The standard voices models are optimized for real-time use cases, and the HD equivalents are optimized for quality.

These new TTS voices augment capabilities, such as building custom voices and avatars, already available in Azure AI and allow customers to build entirely new experiences across customer support, training videos, live-streaming and more.

This capability allows developers to give human-like voices to chatbots, audiobook or article narration, translation across multiple languages, content creation for games and offers much-needed assistance to the visually impaired.

The new voices will support a wide range of languages from Afrikaans to Welsh, and the service can cater to diverse linguistic needs. For a complete list of supported languages, please follow this link.
