Abstract: The human-computer interaction technology of intelligent terminals has totally altered from computer-centered to natural-oriented human-centered paradigm. As the most natural interaction mode of human beings, speech interaction has become a hot topic in both research and application fields in recent years. In the practical application environment of speech interaction technology, a signal recognition and processing method is required to get clean speech from the noisy speech. This paper presents a speech enhancement technique which is based on improved spectrum subtraction by using auditory masking effect, and introduces a novel speech endpoint detection algorithm, which overcomes the influence of music noise and extracts pure speech.

Keywords: Intelligent terminals, Human-computer interaction, Voice detector, Cloud computing.
