Even over a noisy phone line, the transcription of voicemail is extremely good. Whatever speech recognition technology they are using is excellent.
Anybody know what it is?
By the way, Google Voice used to be known as Grand Central before Google bought them.

The secret is not in the
The secret is not in the technology, it's in the methodology. Also, Google is not the first to do this. The original concept was developed by IBM.
The methodology that they use is to continue to collect a large corpus of acoustic data on-the-fly from everyone who calls in voicemail to be transcribed. As the variety and size of the data increases, so does the accuracy.
Nothing special, just a different approach, which is actually what Nuance has done with their speaker independent Acoustic Model.
