Ask HN: What does tropo or twilio use for transcription?
I assumed a custom CMU Sphinx setup, but it doesnt seem that there is a library large enough to support the accuracy they give out. Any ideas?
- jolan 16y agoI'm wondering about this too. CMU Sphinx seems like the obvious solution. Maybe they bought a commercial Sphinx dictionary?
- akalsey 16y agoTropo uses Phonetag.com and Simulscribe to provide the actual transcription, and we've built a custom engine to handle the delivery and management of the transcriptions on the back-end.
