Abstract
The invention discloses a voice control method for a large screen and a terminal, and the method comprises the steps: obtaining a sound signal for voiceprint recognition, and carrying out the semantic recognition of the sound signal in a mode of combining an acoustic model with a language model if the voiceprint recognition is passed, and obtaining a semantic recognition result; and awakening a control program according to the semantic recognition result, and running the control program according to the semantic recognition result to control the large screen. According to the method, in the voice recognition process, the acoustic model is combined with the language model, the voice features and the features of the information in the voice are synthesized, the semantic recognition accuracy is improved, finally, the control program is awakened according to the voice recognition result to control the large screen, and therefore non-contact control over the large screen is achieved; the accuracy of a semantic recognition result is improved through a semantic recognition mode in which voiceprint confirmation is matched with the combination of the acoustic model and the language model.
