STT Engine: Sphinx4 support? #131

Open Holzhaus opened 10 years ago

Holzhaus commented 10 years ago

I just saw a comparison of pocketsphinx and sphinx4. It look's like the recognition of sphinx4 is lightyears ahead of pocketsphinx'.

I hate java, especially on low-end hardware like the RPi, but maybe a Sphinx4-STT-plugin is possible nevertheless.

To archieve this, I think some of this code could be recycled.

What do you think?

That's pretty convincing... I'd definitely be in favour of an STT-plugin, at the very least. Really curious to see how it performs.

+1, the pi 2 has 900MHz and 1Gb Ram, everything is running fast for me. I'm curious to see how it performs

Looks like Sphinx4 still not possible to run on RPi2B. I tried Sphinx4-5prealpha and it need too much memory...

G10DRAS commented 8 years ago

I wrote a simple http web server to host spinx4-5prealpha on a network m/c, Jasper on RPi2B successfully connect to it and use it's STT (just like Google STT) service. But one thing I mark, Speech-To-Text is not that effiecint using Sphinx4 with default Acoustic Model, LM and Dict. To improve efficincy we need to provide custom LM and Dict.
