Abstract

The invention discloses a speech recognition processing method and device. The method comprises: according to speed sample data of all areas of the country, training is carried out on a preset processing model to generate a universal mandarin acoustic model; and on the basis of the speech sample data of all provinces, adaptive training is carried out on the universal mandarin acoustic model respectively to generate mandarin acoustic models with dialectal accents, wherein the mandarin acoustic models corresponding to all provinces. Therefore, on the basis of the accent difference of users at different areas, mandarin acoustic models with dialectal accents are established, so that the speech recognition performance is improved.

Description

technical field [0001] The invention relates to the technical field of voice recognition, in particular to a voice recognition processing method and device. Background technique [0002] The performance of speech recognition is one of the key factors affecting the practicality of speech recognition products. As the main component of speech recognition, the acoustic model plays a key role in the performance of speech recognition. In the training of the acoustic model, how to comprehensively utilize various information to improve the performance and promotion ability of the acoustic model has important theoretical research and practical application value for the speech recognition industry. [0003] Under normal circumstances, the user's Mandarin pronunciation may have a certain degree of dialect accent. For example, in the Mandarin pronunciation of users with a Hunan accent, "h" and "f" often appear indistinguishable, while Mandarin speech recognition products The Mandarin a...
