17. The system of claim 14 , further comprising performing a model level check for an acoustic model that determines a similarity of a TTS phone set and an SR phone set including determining a mapping relation between the TTS acoustic model and the SR acoustic model.
14. A system for determining pronunciation issues, comprising: a processor and memory; an operating environment executing using the processor; text comprising sentences and a recording that corresponds to the text; a Text-To-Speech (TTS) component configured to generate synthesized speech using the text; a Speech Recognition (SR) component configured to recognize speech; and a pronunciation issue detector that is configured to perform actions comprising: receiving the synthesized speech generated by 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; evaluating results obtained from the SR component related to different inputs to the SR component comprising the synthesized speech and the recording; evaluating results from a signal level evaluation of the text and the recording; and generating a list that includes a ranking of pronunciation issue candidates based on the evaluations.
