Hub: Capacity of custom Microsoft Translator Hub systems

Now available: Customize neural and speech translation with the new Custom Translator (Preview)

Custom Translator allows you to customize Microsoft Translator’s neural machine translation when translating text using the Microsoft Translator Text API v3, and speech translation using the preview of the new unified Speech services.

When used with Speech, you can also use the Custom Speech portal to customize speech transcription to better understand the user’s voice, subject matter, or work better in noisy environments, and the Custom Voice portal to customize the text to speech voice output.

When you deploy a custom trained system using the Microsoft Translator Hub, it becomes available via a Microsoft Translator Text API subscription.

The capacity of Hub-trained systems is 300 words per second, or 1800 characters per second. If you need higher capacity, please submit a support request on this site, with your Hub workspace ID and the language pair you need it for .
