Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clear and clear, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The voice recognition continuity control method according to the preferred embodiment of the present invention, as shown in fig. 1, comprises the following steps:
step S10, after receiving the voice recognition wake-up signal, wake-up the voice recognition function, collect the voice signal and carry on voice recognition.
Specifically, after initializing the voice recognition system, the first recognition flag is set to the first flag, for example, the first flag is true, and the delay waiting number (N) is set to 0; then, the voice wake-up detection is started, the voice recognition wake-up signal is received, and when the wake-up condition is judged to be met (the specific signal is detected to wake up the voice recognition process, for example, the specific signal can be a voice command of 'starting voice'), the voice recognition function is woken up (otherwise, in order to avoid the actions of misjudgment, power saving and the like, the voice recognition function is not required to be always started, and can be in a closed state when not woken up), the voice signal of the user is collected, and the voice recognition is carried out.
Step S20, executing the recognized voice command after the voice recognition is successful, and judging whether the intermittent time of the user command exceeds a preset time value after the voice recognition is successful or failed.
Specifically, after the voice recognition is successful, setting an execution stage flag as a first flag (true), feeding back and displaying the content of the voice recognition, executing the recognized voice command, setting a first recognition flag as a second flag (for example, the second flag is false), recording the current time as a recognition starting time point, and setting the delay waiting times as 0; for example, if the voice instruction represented by the voice of the user is successfully recognized to navigate to a certain destination, the user is navigated after the recognition is successful.
Further, in order to achieve the purpose of voice recognition continuity control, that is, to avoid frequent wake-up of the voice recognition function by the user, the present invention provides the following steps: after the voice recognition is successful or failed, judging whether the user instruction intermittence time exceeds a preset time value.
When the voice recognition fails, judging whether the first recognition mark is a first mark (true), if so, setting the first recognition mark as a second mark (false), namely changing the true into false, recording the current time as a recognition starting time point, and setting the delay waiting times (N) as 0; and then delaying the second preset time value (for example, the second preset time value takes 100 ms), increasing the delay waiting time (N) by 1, judging whether the execution stage is a first sign (true), returning to continue delaying the second preset time value if yes, increasing the delay waiting time (N) by 1, and returning to continue collecting and identifying the voice if no.
The user instruction intermittent time=the current time point-the identification starting time point-the delay waiting time number is a second preset time value, and the user instruction intermittent time is the time obtained by subtracting the voice instruction execution time based on the interval time of the two instructions of the user.
Step S30, if yes, the voice recognition function needs to be awakened again when the voice recognition is performed again, and if not, the voice signal is continuously collected and recognized.
Specifically, when the voice recognition is successful, setting a 'first recognition mark' as false, recording the current time as a 'recognition start time point', and setting the delay waiting times N as 0, which is equivalent to the detection of re-entering a new round of 'user instruction intermittent time' by taking the delay waiting times N as a starting point; and (3) carrying out voice command execution and simultaneously using a loop to delay the end of voice command execution, thereby obtaining delay waiting times N, and then entering a voice acquisition and recognition process to continue the voice recognition of the next round.
When the voice recognition fails, calculating whether the 'user instruction intermittent time' (equal to the current time point-the 'recognition start time point' -N is 100 ms) exceeds a set time value (the value can be determined according to the time consumption required by the voice recognition under normal conditions, the time consumption is taken to be 2-3 times, for example, the value is 10 s), and if the time is not overtime, continuing to acquire and recognize the next voice; if the voice recognition function is overtime, the continuous dialogue is judged to be ended, the voice collection and recognition flow is not entered any more, and the flow before voice awakening is entered, and the user waits for the next awakening (activating) of the voice recognition function.
According to the invention, the continuity of the voice recognition process can be improved, so that the user can continuously communicate with the voice recognition equipment without frequent activation within a certain pause interval time, and the intelligent terminal is more convenient for the user to operate and use.
Further, as shown in fig. 2, based on the above-mentioned voice recognition continuity control method, the present invention further correspondingly provides a voice recognition continuity control device, where the voice recognition continuity control device includes: the voice activation detection module 11 is configured to wake up a voice recognition function after receiving a voice recognition wake-up signal; a voice acquisition and recognition module 12 for acquiring voice signals and performing voice recognition; the voice recognition continuity judging module 13 is configured to judge whether the user instruction intermittence time exceeds a preset time value after the voice recognition is successful or failed; the voice execution module 14 is configured to execute the recognized voice command after the voice recognition is successful.
According to the invention, the continuous experience of interaction between a user and voice recognition equipment (intelligent terminal) is improved by adding the voice recognition continuity judging module, namely, after each voice recognition, the user instruction intermittence time is calculated (the running time of the voice execution module is filtered out), and the next voice recognition process is circularly initiated under the condition that the preset time value is not exceeded, so that the purpose of continuous communication between the user and the voice recognition equipment under the condition that frequent activation is not needed is achieved.
