1. A method for determining pronunciation issues, comprising: receiving text comprising sentences for a Text-To-Speech (TTS) component and a recording of the text that is used as a reference for the text; receiving synthesized speech generated by the TTS component using the text as input to the TTS component; evaluating results received by an evaluation performed at a text level by determining a similarity of the synthesized speech to the recording, wherein the evaluation at the text level comprises performing a similarity measurement of a phone sequence of a sentence in the text and a corresponding phone sequence of a sentence in the recording; evaluating results obtained from a Speech Recognition (SR) component related to different inputs to the SR component comprising the synthesized speech and the recording; and generating a list that includes a ranking of pronunciation issue candidates based on the evaluations.

The method of claim 1 , wherein the evaluation performed at the text level comprises determining a similarity using an equation as defined by: s = 1 - C Sub + C Ins C Corr + C Sub + C Del where s is a similarity score; C Corr , C Sub , C Ins and C Del denote counts of correct components, substitution errors, insertion errors, and deletion errors in a sentence.
