Azure Neural Text to Speech (Azure Neural TTS), a powerful speech synthesis capability of Azure Cognitive Services, enables developers to convert text to lifelike speech using AI. Enterprises and agencies utilize Azure Neural TTS for video game characters, chatbots, content readers, and more. The Azure Neural TTS product team is continuously working on bringing new voice styles and emotions to the US market and beyond.

New voice styles and emotional tones

We received feedback from customers that more voice options would help them better apply Azure Neural TTS to different user scenarios. In addition, supporting voice emotions and voice styles would help deliver the most engaging experience to end-users. With that feedback, we decided to add five new neural voices in US-English, expanding from 15 to 20. This includes two female voices—Jane and Nancy—and three male voices—Davis, Jason, and Tony. We also expanded to eight emotional tones for many of our existing and new voices, including cheerful, angry, sad, excited, hopeful, friendly, unfriendly, and terrified. Finally, to improve spatial experiences, we added shouting and whispering.

New ways to project

We encourage you to try the new voices and emotions. Feedback is encouraged to help inform which voices will be made for General Availability in all regions, depending on customer satisfaction. “By supporting more voice options and expanding voice styles, Azure Speech continues to address the unmet needs of the customers to build more delightful speech experience," said Binggong Ding, Principal Group Product Manager of the Microsoft Speech team.

Three ways customers are using this

Content reading is a popular use case for AI customers using Azure Neural TTS. Microsoft has plugins to enable Read Aloud across the web. This use case also supports improved accessibility for customers with vision challenges. The new voice style, supported by ten different emotional tones creates endless possibilities for improving the customer experience. Scaling character voice production is accelerated by Azure Neural TTS. Video game characters with lifelike voices can be trained quickly to bring your virtual worlds to life and delight gamers. Emotional tones for being terrified and friendly help add more personality to the game experiences. Long gone are the days of frustrating voice assistants and chatbots, as now you can deliver lifelike conversational experiences. Call centers can scale operations while also improving customer satisfaction.
