Cognitive Services Pricing – Custom Speech Service PREVIEW

Use intelligence APIs to enable vision, speech, language and knowledge capabilities

The Custom Speech Service lets you create custom speech recognition models and deploy them to a speech-to-text endpoint that’s tailored to your application. With Custom Speech Service, you can customise the language model of the speech recogniser, so it learns the vocabulary of your application and the speaking style of your users. You can also customise the acoustic model of the speech recogniser to better match the application’s expected environment and user population.

Pricing details

Each pricing tier provides a certain concurrent transcription rate. Customers can then choose to import text data for custom language model creation or acoustic data, audio plus transcriptions and for custom acoustic model creation.
