Add the word zero to your pronunciation dictationary, re-run script

hi ken,

         zero is already there in the pronunciation dictionary. there is still the same problem.

>zero is already there in the pronunciation dictionary

add a prompt in step 2 of the Howto with the word zero, e.g.:

*/sample32 ZERO ZERO ZERO ZERO ZERO ZERO

record the new prompt in Step 3,

re-run the script. in Step 4.

Thanks for your response.

Just to clarify what I'm trying to do. I am not interested in the words spoken, just the phonemes present in an audio file and their durations/timing information i.e. the start and end of each phoneme.

Hi Ken,

         Please could you give me some pointers on how to find the timing information of the phonemes. The start and end of each phoneme. I have to generate .lab files with the phone separation along with their timing for each sample speech file recorded.

Thank you very much.

if you are looking for something like this:  aligned.out , then check out how to do force alignment on this page: Automated Audio Segmentation Using Forced Alignment (Draft)

Hi Ken,

          Thank you very much for the quick response. Yes, I am trying to get a result like that. But the thing, is I am trying to do a free alignment not forced so do you have any suggestions about that? 

Thank you

>free alignment

How is this different than forcd alignment?

Hi Ken,

In forced alignment the speech recognition system is given apriori information about the words and phonemes that are uttered. The system therefore looks for *all* phonemes in the words even when speech is fast and sloppy and phonemes are dropped or mispronounced. Furthermore, in forced alignment, the system also looks for or forces pauses between words even when the pauses do not exist. (No one really pauses between words.)

In free alignment however, the system is not given apriori information about what words are uttered, and the system is free to find search for whatever phonemes are uttered only. As such pauses are only found where they truly exist. 

Thank you.
