The present invention will be described in detail with reference to the following specific examples:
the present invention is described below by taking an air conditioner as an example:
the voice air conditioner is more and more popular, and the voice air conditioner is usually awakened by recording a segment of audio recognition awakening words in the market. Since people also talk about the awakening word in the communication process, the awakening word is mistakenly recognized, and troubles are caused to users.
In fact, the audio is in the form of sound waves spread in the time dimension, and whether the audio is similar or the same can be judged by analyzing the wave fronts (ripples, waves) and comparing the wave fronts (ripples, waves). The analogy to the KTV scoring software and the song listening and identifying software is based on the pitch, rhythm and your score and judge which song is, which is identified by the pop (or wave, waveform) of the audio.
The traditional voice air conditioner is only awakened by awakening words and phrases, so that false awakening is easy to occur, and the recognition rate is low; the traditional air conditioner awakening mode is uninteresting, and if the traditional air conditioner awakening mode is used for simultaneously identifying the tone and the rhythm through awakening word interception. Based on this, the present embodiment provides a way that the keyword and its tone and rhythm reach the predetermined value at the same time (instead of just meeting the keyword), and the air conditioner can be woken up.
The embodiment mainly comprises the following steps: the threshold value and the calculation method for waking up the air conditioner by combining the wake-up word with the tone and rhythm are customized for the voice air conditioner, so that a user can wake up the air conditioner in a singing input mode, the error recognition rate is reduced, and the wake-up interestingness is improved.
Fig. 6 is a flowchart (one) of the wake-up work of the voice air conditioner in this embodiment, which specifically includes the following steps:
s601: acquiring a current audio signal input by a user;
s602: and after the non-human voice is removed, analyzing the semantics in the audio signal. And forming a command word after the semantic analysis is successful, and comparing the command word with a preset awakening word.
S603: when the command word contains the preset awakening word, a series of signal processing methods are adopted to carry out spectrum matching analysis on the audio signal. And if the audio signal matching degree is greater than the threshold value, the voice awakening command is considered to be successfully identified.
S604: and acquiring a voice awakening command code, and sending the awakening command code to the air conditioner, wherein the air conditioner has the function of awakening the voice.
The embodiment solves the technical problem that the awakening mode of the voice control mode in the prior art easily causes mistaken awakening or recognition rate, and achieves the effect of simply, accurately and interestingly awakening the air conditioner.
Fig. 7 is a flowchart (ii) of the wake-up work of the voice air conditioner in this embodiment, which specifically includes the following steps:
s701: voice collection;
s702: removing the non-human voice;
s703: judging whether voice exists or not, if so, turning to S704, otherwise, turning to S701;
s704: and (3) semantic parsing:
s705: judging whether the word is a wake-up word, if so, turning to S706, otherwise, turning to S703;
s706: processing the audio signal;
s707: judging whether the matching degree of the tone and the rhythm in the audio signal is greater than a threshold value, if so, turning to S708, otherwise, S701;
s708: recognizing a voice wake-up command;
s709: acquiring a wake-up command code;
s710: the air conditioner executes the wake-up command code.
In conclusion, due to the adoption of the awakening mode of combining the awakening words with the tone and the rhythm, compared with the traditional voice air conditioner, the identification rate and the awakening efficiency are improved, and the interestingness is increased.
