Embodiment Construction
[0082] The embodiment of the present invention provides a voice information recognition method and a terminal device, which extract voiced sound information from the voice information to be recognized, extract pitch frequency parameters and MFCC from the voiced sound information, and process the pitch frequency parameters to obtain pitch frequency parameter matching values; The MFCC is processed to obtain the MFCC parameter matching value; the characteristic information of the speech information to be recognized is determined according to the pitch frequency parameter matching value and the MFCC parameter matching value.
[0083] Human speech can be roughly divided into two parts: unvoiced and voiced. The voiced segment is characterized by a relatively high energy distribution, has the periodicity of the voice fundamental tone, has a formant structure in the frequency domain, and most of the energy is concentrated in the low frequency band. Inside. The amplitude of unvoiced so...
