They have been active at Cluecon and have a web API
that does fully hosted ASR on WAV's or MP3's.

They are doing innovation around running their ASR in GPU clusters,
which means their internal cost of operation is likely to be the lowest in
the industry.

Good ASR is always going to be computationally intensive,
so it is helpful to have somebody managing that for you.
It's going to be a lot easier that trying to juggle your own sphinx training
