Claim One:
1. A computer server system for automatically determining suitability of at least a portion of a speech signal, comprising voice data, for statistical modeling, the system comprising: a memory storing computer code instructions thereon; and a processor, the memory, with the computer code instructions, and the processor being configured to cause the computer server system to implement: a modelability estimator configured to: determine a statistical modelability score of the at least a portion of the speech signal comprising voice data, the statistical modelability score indicating favorability of the at least a portion of the speech signal for statistical modeling in terms of human perception and based at least in part on determining a temporal stationarity of the at least a portion of the speech signal comprising voice data; and forward the statistical modelability score to a speech synthesis system executed by the processor, wherein the speech synthesis system is configured to utilize the modelability score in converting text to speech; and a decision maker configured to determine a preferred speaker selection for use by the speech synthesis system in building a statistical text-to-speech system based on the statistical modelability score determined for speech provided by each of a plurality of speakers.
