    • Disclosed is a speech recognition method and apparatus that includes a process of compensating a degraded speech by a speech coder in order to prevent deterioration of speech recognition performance by the speech coder and improve the speech recognition performance when a voice signal is inputted to the speech recognition apparatus, not directly, but after that the voice signal is reproduced by compressing and decoding processes of the speech coder while transferring the voice signal through a digital communication network after the voice signal is generated. The speech recognition method and apparatus according to the present invention include a process of increasing the speech recognition performance when training the speech recognition apparatus with only an original voice signal not passing through the speech coder or with both the original voice signal and a signal degraded by the plurality of voice compressors, and a process of compensating a degradation by the speech coder regardless of the type of the speech coder.

    • Disclosed is a transmit power control outer loop for improving a speech recognition success rate in a mobile communication system, which adaptively controls a target Frame Error Rate as a target power control value corresponding to a Speech Recognition Success Rate by adding a Speech Recognition Rate Management outer loop to a power control loop wherein the power control loop consists of an inner loop and an outer loop. In order to achieve that, in the transmit power control loop for improving speech recognition success rate, a Speech Recognition Rate Management outer loop having a Speech Recognition Success Rate estimator is included to an outer loop. Speech Recognition Success Rate estimator estimates the rate of successful recognition from received voice frames. Speech Recognition Rate Management outer loop compares estimated Speech Recognition Success Rate with target Speech Recognition Success Rate and automatically adjusts the target Frame Error Rate according to the compared result.
    • 公开了一种用于改善移动通信系统中的语音识别成功率的发送功率控制外部环路,其通过将语音识别率管理外部添加来自适应地将目标帧错误率控制为对应于语音识别成功率的目标功率控制值 循环到功率控制回路,其中功率控制回路由内部回路和外部回路组成。 为了实现这一点,在用于提高语音识别成功率的发送功率控制环路中,具有语音识别成功率估计器的语音识别率管理外部循环被包括到外部循环中。 语音识别成功率估计器估计从接收的语音帧成功识别的速率。 语音识别率管理外环将估计的语音识别成功率与目标语音识别成功率进行比较,并根据比较结果自动调整目标帧错误率。
