[0023] The adaptive method for pronunciation evaluation of computer language learning system includes the following steps:
[0024] 1. The steps for building a speech recognition system are as follows:
[0025] (1) Collect training recognizer speech;
[0026] (2) Data labeling;
[0027] (3) Training of consonants and vowel models;
[0028] (4) Tone model training;
[0029] (5) Save the model to the computer-aided language learning system library.
[0030] 2. Perform segmentation and limit boundary recognition based on the recognizer, the steps are as follows:
[0031] (1) Statistics of the replacement list of consonants and vowels: According to the prior knowledge of experts, the phonemes that are easily confused by the speaker are counted as candidates for boundary recognition. This has two advantages: First, it simplifies the calculation and makes the posterior probability Calculation is more convenient and faster. Second, it reduces the influence of a...
