Create a voice as unique as your business

Do you need to give your voice agent a unique, recognizable brand voice? The Text-to-Speech voice customization feature makes it easy to create one-of-a-kind voice-enabled apps, with no expertise required. To customize your voice agent, simply record and upload training data, and Microsoft creates a unique voice font tuned to your recording. The system easily scales as you get more data to provide an even more natural voice.

When using either default or customized voices, you can further tailor your audio by controlling parameters such as the speed of speech, pitch, volume, additional pauses, and pronunciations.

Creating a custom voice model

1 Prepare training data and create a Speech Services subscription before you start to train a Custom Voice.

2 Upload your data to the Custom Voice portal or through the Custom Voice API and check quality.

3 Use your data to train a custom model. Test the model with your script when it’s ready.

4 Deploy the voice model to get your custom API endpoint. Test the endpoint before you integrate it in your system.

5 Use the voice in your apps by using code samples from the endpoint.
