1. A method comprising:
- determining a phoneme distribution of a text corpus;
determining an acoustic model gain distribution of phonemes of an acoustic model before and after adaptation of the acoustic model;
determining a desired phoneme distribution based on the phoneme distribution and the acoustic model gain distribution;
generating an adaption sentence based on the desired phoneme distribution; and
generating a prompt requesting a user speak the adaptation sentence.

Abstract
Methods and systems for adapting of acoustic models are disclosed. A user terminal may determine a phoneme distribution of a text corpus, determine an acoustic model gain distribution of phonemes of an acoustic model before and after adaptation of the acoustic model, determine a desired phoneme distribution based on the phoneme distribution and the acoustic model gain distribution, generate an adaption sentence based on the desired phoneme distribution, and generate a prompt requesting a user speak the adaptation sentence.
