You said - "HTK requires Pronunciation Dictionnary with at least 30-40 'sentences' of 8-10 words each.  If your Grammar has fewer sentences/words than this (as we do in this tutorial), or if your grammar in not  phonetically balanced (if some phonemes only occur one or two times) then we need to add additional words to make sure we have 3-5 occurences of each phoneme in our Pronunciation Dictionnary."

I have 2 minutes AUDIO recording file (.wav) spoken in 10 - 15 sentences. I have few queries in writing the 'prompts' file -

1. Assuming 2 sentences being spoken than each sentence has to be written in separate NEW LINE as -

*/AUDIO1 I EAT FOOD
*/AUDIO2 I DO EXERCISE

OR

2. It has to be written as -

*/AUDIO1 I EAT FOOD I DO EXERCISE

OR

3. */AUDIO1 I EAT FOOD. I DO EXERCISE.

4. This sentences has to be written in BLOCK letters always.

Please respond.

> I have 2 minutes AUDIO recording file (.wav) spoken in 10 - 15 sentences. 

You need to split audio on smaller parts containing individual sentences: audio1, audio2, audio3

> 1. Assuming 2 sentences being spoken than each sentence has to be written in separate NEW LINE as -

So, what I understand is with multiple sentences, one has to simply BREAK into equal length of words and write in seperate NEW LINE.

BTW', how does one get these ideas of implementing?

Thanks a lot .. nsh!!

Not necessary the equal length of words. You simply put every new prompt on a new line.

Let's say that I had 5 sentences based audio recording file (X.wav) of 2 minute as - "I eat apple. I like apple very much. An apple a day keeps doctor away. Eating an apple maintains good amount of vitamin K. Thank you very much for such a valuable information." which I have represented in 'prompts' file as -

*/X1 I EAT APPLE

*/X2 I LIKE APPLE VERY MUCH

*/X3 AN APPLE A DAY KEEPS DOCTOR AWAY

*/X4 EATING AN APPLE MAINTAINS GOOD AMOUNT OF VITAMIN K

*/X5 THANK YOU FOR SUCH A VALUABLE INFORMATION

Now, I should have single audio file as 'X.wav' or multiple audio files as "X1.wav, X2.wav, X3.wav, X4.wav and X5.wav" in "../train/wav' folder with each multiple audio files "X1.wav - X5.wav" as a copy of X.wav file.

Really appreciate your help.

You should have multiple files - X1, X2, X3 and so on

Each file must be a part of big file X, not a copy of it. Each file must contain recording of the correponding sentence.
