Introduction

At PlayHT, our vision is to redefine human interactions with AI agents. Whether it’s for customer support or sales calls, AI tutors, or bringing Gaming NPCs to life, our goal is to revolutionize the way humans communicate with generative AI agents.

Today we announce our latest milestone on the road to fulfilling that vision: the launch of PlayHT Turbo, a new version of our conversational voice model, PlayHT 2.0 that generates speech in under 300ms via network and < 100ms for on-premise solutions.

Input Text Streaming

PlayHT 2.0 Turbo supports input text streaming. This feature seamlessly integrates with LLMs, like chatGPT. Simply feed the output stream of tokens/words from the LLM and the SDK will process the tokens in the best way that can balance both generating expressive contextual speech and reducing the TTFB (time to first byte).

Output Speech Streaming

Once Turbo receives text, it starts streaming audio in approximately 70ms. However, due to inevitable network costs, users typically receive the audio stream within a 200ms to 400ms window.

Check out our demo showcasing the integration with chatGPT with both input and output streaming:
