Hi aninudh291,

Welcome to the Apple Community.

Seems Siri heard you, but didn't understand your words / what you said.

Siri wanted you to say it again. ("Try again")

Siri works by hearing the sound of your voice:

Just say "Hey Siri" and ask your question.

Try clicking the link below, and scroll down to this info:

       If Siri seems to hear you but not understand you,:

       make sure that your language and dialect are selected in Siri preferences.

       (Siri is not available in all languages, countries or regions.)

if speech is difficult or you don’t want others to hear your Siri requests.:

You can enable the setting "Type to Siri" (use keyboard instead of voice).
