Twilio announced a new partnership with OpenAI, adding the ability to build conversational, artificial-intelligent powered agents on the communication-tools provider's platform.

The San Francisco company said Tuesday that, as a result of the partnership, over 300,000 of its customers and more than 10 million developers will be able to build these AI agents.

Terms of the partnership weren't disclosed. Twilio said the agreement builds on the companies' existing product integrations announced last year.

The partnership will integrate OpenAI's Realtime API's streaming speech-to-speech capabilities, which allow for voice conversations by AI virtual agents to more-closely resemble human dialogues, to Twilio's platform. OpenAI's Realtime API reduces latency and improves conversation pacing, interruption handling, tone and balance between speaking and listening, according to the company.

This integration will make it possible to build, deploy and serve customers with virtual agents on a single platform. Twilio said the technology is especially relevant for customer service and sales, adding it can also be used for voice translation in real time between constituents and staff members who speak different languages.

News Corp, owner of The Wall Street Journal and Dow Jones Newswires, has a content-licensing partnership with OpenAI.
