We'd like to remind readers that the responses to queries are usually
best posted to the individual asking the question. That individual is
then strongly encouraged to post a summary to the list. This policy was
instituted to help control the huge volume of mail on LINGUIST; so we
would appreciate your cooperating with it whenever it seems appropriate.

In addition to posting a summary, we'd like to remind people that it
is usually a good idea to personally thank those individuals who have
taken the trouble to respond to the query.

My company is developing software for doctors to dictate reports. Our
software relies on a speech recognition engine that is trained to 
recognize words.  To improve on the current model, I am redesigning 
the initial speech training component.  As I would like to develop 
effective material, I am looking for insight on the following questions:

What are the requirements for initial speech training text (to be read by
the user of speech recognition in order to initially train the speech
engine, and start working with a satisfactory level of recognition)?  
Does it have to include all possible phonemes of a language? 
Do they have to repeat certain number of times? 
If the full phonemic inventory is not required, what would be necessary 
for a language such as English?  
What other requirements should I consider for such a text?

While I have attempted to do some research on this subject, I have had
trouble finding adequate guidelines for this, and speech corpora have 
not really been searchable for texts like this.  I have an exemplary text 
of SpeechMagic software (provided by Nuance), but I would be grateful 
for any additional examples people could provide.  Any other resources 
or guidelines for speech recognition development would also be greatly
appreciated.
