Re-translation for simultaneous, spoken-language machine translation

A system comprising:

• one or more computers;
• and
• one or more computer-readable media storing instructions that, when executed by the one or more computers, are operable to cause the one or more computers to perform operations comprising:
• receiving, by the one or more computers, a stream of audio data comprising speech in a first language;
• generating, by the one or more computers, a transcription for the speech in the stream of audio data using an automated speech recognizer, the transcription being incrementally generated by the automated speech recognizer through a series of updates that add additional text in the first language to the transcription;
• generating, by the one or more computers, a translation of the transcription into a second language using a machine translation module, the translation being generated by performing, in response to each of the updates that add additional text in the first language to the transcription, a corresponding translation iteration that translates into the second language an end portion of the transcription, wherein the end portion at least some of the translation iterations comprises (i) the additional text corresponding to the update and (ii) previously-translated text of the transcription, wherein, for at least some of the translation iterations, the one or more computers promote stability of the translation by biasing output toward including the previously-translated text of the transcription;
• and
• providing, by the one or more computers and over a communication network, a series of translation updates to a client device based on the translation iterations, wherein the translation updates respectively provide portions of the translated text from the corresponding translation iterations.

One or more non-transitory computer-readable media storing instructions that, when executed by one or more computers, are operable to cause the one or more computers to perform operations comprising:

• receiving, by the one or more computers, a stream of audio data comprising speech in a first language;
• generating, by the one or more computers, a transcription for the speech in the stream of audio data using an automated speech recognizer, the transcription being incrementally generated by the automated speech recognizer through a series of updates that add additional text in the first language to the transcription;
• generating, by the one or more computers, a translation of the transcription into a second language using a machine translation module, the translation being generated by performing, in response to each of the updates that add additional text in the first language to the transcription, a corresponding translation iteration that translates into the second language an end portion of the transcription, wherein the end portion at least some of the translation iterations comprises (i) the additional text corresponding to the update and (ii) previously-translated text of the transcription, wherein, for at least some of the translation iterations, the one or more computers promote stability of the translation by biasing output toward including the previously-translated text of the transcription;
