August 01 Presto - The new project/Presto - O novo projetoNow that TBot is stable, and the new version is almost ready, it’s time to start playing with other prototypes. After more than 2 years interacting with TBot users I can say that I learned a lot, and that one of my first assumptions still holds true; people do adapt to get better results of the tools they use. Based on that I’ve been investigating yet another way to combine existing pieces of technology to build something new. Everyone know that Microsoft has made significant investment on speech recognition and synthesis, so it is possible – at least in theory – to put it all together and build a Speech to Speech translation application. No, I’m not talking about Captain Kirk’s Universal Translator – yet… Project Presto is still very limited, but it does work – and if you use simple, short sentences the results can be pretty good. Here are two videos: English to Portuguese and English to Japanese (Takako help me select sentences that would provide better translations for Japanese) As you can see, Presto relies on the fact that open dictation grammars work pretty well for short utterances – in other words, breaking long sentences in small chunks makes it easier for the speech recognizer to work. The awkward pauses you’ll see between some sentences are necessary because of a bug in the prototype – the function that plays audio is not detecting the end of the stream correctly. Presto uses Microsoft technology all the way – from the speech recognition to translation and then text-to-speech. I’ve added the camera feed support for two reasons: first, because Presto can be used as a presentation tool (hey, it’s ideal for conferences!); second, because in the future this technology added to some of the existing collaboration/communication products. Other uses may include video authoring, virtual classrooms, etc… I don’t expect that Presto will follow TBot’s footsteps and become a product, but I’m hoping that it can raise attention to the possibilities of similar technologies. Enjoy the videos! Helvecio English - Portuguese |
