Speakerphone and server device for environment acoustics determination and related methods

A server device comprising one or more processors comprising machine learning circuitry configured to operate according to a machine learning model, one or more interfaces, and a memory, wherein the server device is configured to:

• obtain, via the one or more interfaces, from one or more speakerphones, one or both of an impulse response associated with an environment and one or more environment parameters indicative of acoustics of the environment;
• train the machine learning model based on one or both of the impulse response and the one or more environment parameters for provision of an updated machine learning model;
• and
• transmit the updated machine learning model to at least one of the one or more speakerphones.

A method of operating a speakerphone system comprising one or more speakerphones including a first speakerphone comprising a processor, a memory, an interface, a speaker, and one or more microphones including a first microphone, and a server device, the method comprising:

• obtaining, using the first speakerphone, an internal output signal for provision of an internal audio output signal in an environment;
• outputting, using the first speakerphone and based on the internal output signal, an internal audio output signal in the environment;
• obtaining, using the first speakerphone, a microphone input signal, wherein the microphone input signal is a resulting signal after the internal audio output signal is outputted by the speaker in the environment;
• determining, using the first speakerphone and based on the internal output signal and the microphone input signal, an impulse response associated with the environment;
• determining, using the first speakerphone, based on the impulse response, one or more environment parameters indicative of acoustics of the environment, the one or more environment parameters including a first environment parameter;
• transmitting, from the first speakerphone, one or both impulse response and the first environment parameter to the server device.
