New and improved translation models now available for 8 languages
That Translator uses Microsoft Translator speech translation technology to power its solution. Therefore, That Translator customers benefit from all the improvements Microsoft releases without the need of updating anything on their end.
The Microsoft Translator team announced that the translation models for Chinese, German, French, Hindi, Italian, Spanish, Japanese, Korean, and Russian (from and to English) have been updated to take advantage of the latest Neural Machine Translation advances coming out of their research team.
Although these improvements are significant from an engineering quality metrics perspective, it's also important to keep in mind that these are calculated over a broad range of conversational text and, as the saying goes, your "mileage may vary" depending on your unique situation. Also important to notice are that these improvements only refer to the translation part (once the user's voice has been converted to from speech to text), not the speech recognition part.
More technical details on these changes are available on the team blog: www.microsoft.com/en-us/translator/blog/2019/06/17/neural-machine-translation-enabling-human-parity-innovations-in-the-cloud/
As indicated above, That Translator customers don't need to update anything. Their system is already using these latest AI algorithms by default.
