Speech signal processing method and related device

An electronic device, wherein the electronic device comprises a processor and a memory, the processor is coupled to the memory, and the processor is configured to perform, based on instructions stored in the memory, speech signal processing that causes the electronic device to:

• obtain a first speech signal captured by a first pickup unit, wherein the first speech signal comprises an environmental noise signal, and the environmental noise signal indicates environmental noise of an environment in which a wearable device is located;
• while performing a voice service using a second speech signal captured by a second pickup unit of the wearable device, obtain first duration based on the first speech signal, wherein the first duration is duration in which noise energy of the environmental noise signal is continuously greater than a first energy threshold currently;
• and
• determine, based on the first duration, whether to switch to using a third speech signal to perform the voice service, wherein the third speech signal is captured by a third pickup unit of the wearable device, and when the noise energy of the environmental noise is greater than the first energy threshold, a signal-to-noise ratio of the third speech signal is greater than a signal-to-noise ratio of the second speech signal.

A non-transitory computer-readable storage medium comprising instructions, wherein when the computer-readable storage medium runs on a computer, the computer is enabled to perform speech signal processing that causes the computer to:

• obtain a first speech signal captured by a first pickup unit, wherein the first speech signal comprises an environmental noise signal, and the environmental noise signal indicates environmental noise of an environment in which a wearable device is located;
• while performing a voice service using a second speech signal captured by a second pickup unit of the wearable device, obtain first duration based on the first speech signal, wherein the first duration is duration in which noise energy of the environmental noise signal is continuously greater than a first energy threshold currently;
• and
• determine, based on the first duration, whether to switch to using a third speech signal to perform the voice service, wherein the third speech signal is captured by a third pickup unit of the wearable device, and when the noise energy of the environmental noise is greater than the first energy threshold, a signal-to-noise ratio of the third speech signal is greater than a signal-to-noise ratio of the second speech signal.
