I believe those (u092e, etc) are Hindi Unicode characters. Whatever software you're using to convert those characters into speech apparently doesn't handle them. You need to check its documentation relating to non-English Unicode to see if it can be enabled, or switch to another package that supports Hindi text-to-speech.
UPDATE
With the additional information that the package used is espeak, it looks like it does have a Hindi language option. Unfortunately the documentation describes this option as 'initial naive implementations which have had little or no feedback and improvement from native speakers', so your results may be less than spectacular.
From the espeak documentation on language files:
A number of Voice files are provided in the espeak-data/voices
directory. You can select one of these with the -v
parameter to the speak command, eg:
espeak -vaf
to speak using the Afrikaans voice.
In your case the appropriate option is hi for Hindi, per the ISO 639-1 standard. You'll need to run espeak using that parameter:
espeak -vhi
