Abstract
A system and method for selecting a speech-to-text engine are disclosed. The method includes selecting, by an engine selection component, at least two speech-to-text engines to decode a portion of computer-readable speech data. The portion of speech data can be decoded simultaneously by the selected speech-to-text engines for a designated length of time. In some embodiments portions of the speech data can be simultaneously decoded with selected speech-to-text engines at periodic intervals. An accuracy of decoding can be determined for each selected speech-to-text engine by an accuracy testing component. Additionally, the relative accuracies and speeds of the selected speech-to-text engines can be compared by an output comparison component. The engine selection component can then select the most accurate speech-to-text engine accurate to decode a next portion of speech data. Further, the engine selection module may select a speech-to-text engine that meets or exceeds a speed and/or accuracy threshold.
