Warning a user when voice input to a device is likely to fail because of background or other noise

摘要

Methods and devices are disclosed for notifying a user of a likelihood of successful recognition in an environment by a voice recognition application. In one embodiment, the method includes a device recording a noise sample in an environment and making a comparison of the noise sample and at least one predetermined threshold. The method further includes, based on the comparison, determining a likelihood of successful recognition in the environment by a voice recognition application, and triggering a notification indicating the likelihood. In another embodiment, the device includes a microphone configured to record a noise sample in an environment, a processor, and data storage comprising instructions executable by the processor to make a comparison of the noise sample and at least one predetermined threshold, based on the comparison, determine a likelihood of successful recognition by a voice recognition application, and trigger a notification indicating the likelihood.
