In a device (100), a method (200) is provided for improving text-to-speech performance. The method includes the steps of determining (202) if a text expression from an application operating in the device is in a vocabulary, selecting (204) a corresponding speech expression from the vocabulary if the text expression is included therein, synthesizing (206) the text expression into a corresponding speech expression if the text expression is not in the vocabulary, playing (208) said speech expression audibly from the device, monitoring (210) a frequency of use of said text expression, storing (212) said text expression and corresponding speech expression in the vocabulary if the frequency of use of said expression is greater than a predetermined threshold and said expressions were not previously stored, eliminating (214) one or more text expressions and corresponding speech expressions from the vocabulary if the frequency of use of said expressions falls below the predetermined threshold, and repeating the foregoing steps during operation of the application. An apparatus implementing the method is also included.
