Embodiment

[0027] Such as figure 1 As shown, the digital real estate display system based on voice interaction includes a voice feature extraction module, a voice model and pattern matching module, and a control module. The module is the underlying model of the recognition system and is the most critical part of the speech recognition system. The speech model is usually generated by training the acquired speech features. The purpose is to establish a pronunciation template for each pronunciation, and to combine unknown speech features with Speech models are matched and compared, the distance between the feature vector sequence of unknown speech and each pronunciation template is calculated, and the recognition results are analyzed for grammar and semantics. The speech model and pattern matching module includes a preprocessing unit, a feature extraction unit, and pattern recognition. , training unit, the preprocessing unit includes pre-emphasis, windowing and framing and endpoint detectio...

Abstract

The invention discloses a digital building presentation system based on voice interaction, which comprises a voice feature extraction module, a voice model and mode matching module, and a control module, wherein the voice feature extraction module extracts a voice feature sequence changing over time from a voice waveform; the voice model and mode matching module matches and compares unknown voice features with the voice models in the case of recognition, the distance between a feature vector sequence of the unknown voice and each sound production module is calculated, and syntax and semantic analysis is carried out on a recognition result; and the control module performs corresponding house type presentation control on a computer system according to a result outputted by the voice model and mode matching module. According to the digital building presentation system based on voice interaction, environmental adaptability is strong, the recognition rate is high, modal particles in the case of continuous voice recognition can be removed, control on building presentation can be carried out, and the full view of the building can be presented in real time through voice interaction.

Description

technical field [0001] The field of speech recognition of the present invention, more specifically relates to a digital real estate display system capable of speech interaction. Background technique [0002] With the rapid development of modern science and technology, information resources have become more and more important. Communication or information exchange has become a necessary condition for the existence of human society, and it has also become a decisive factor in the future battlefield. Language is what distinguishes humans from animals. Speech is the phonetic expression of language, and it is the most important, effective and convenient form of information exchange for human beings to transmit information. Some speech recognition systems have come out one after another. The task of the speech recognition system is to enable machines to understand human language, that is, to convert human speech signals into corresponding text, instructions or control signals thro...
