Method for recognizing speech to avoid over-adaptation during online speaker adaptation

   
   

To avoid an over-adaptation of a current acoustic model (CAM) to certain and frequently occuring words for speech phrases during on-line speaker adaptation of speech recognizers it is suggested to count adaptation numbers (a.sub.j) for each of said speech phrases (SPj) as numbers of times in that a distinct speech phrase (SPj) has been used as a basis for adapting said current acoustic model (CAM) and further to make the strength of adaptation of the current acoustic model (CAM) on the basis of said distinct speech phrase (SPj) dependent on its specific adaptation number (a.sub.j) so as to decrease the influence of frequent speech phrases (SPj) in the received speech flow on the adaptation process.

Para evitar una sobre-adaptacio'n de un modelo acústico actual (LEVA) a palabras ciertas y con frecuencia que ocurren para las frases del discurso durante la adaptación en línea del altavoz de los reconocedores del discurso se sugiere para contar los números de la adaptación (a.sub.j) para cada uno de las frases dichas del discurso (SPj) como números de épocas en que se ha utilizado una frase distinta del discurso (SPj) como una base para adaptar el modelo acústico actual dicho (LEVA) y hacer más lejos la fuerza de la adaptación del modelo acústico actual (LEVA) en la base del dependiente distinto dicho de la frase del discurso (SPj) en su número específico de la adaptación (a.sub.j) tan como disminuir la influencia frecuente del discurso frases (SPj) en el flujo recibido del discurso en el proceso de la adaptación.
