Sound signal processing system apparatus for avoiding adverse effects on speech recognition

A sound signal processing apparatus configured to be communicatively connected to an information processing apparatus, the sound signal processing apparatus comprising:

• a signal processing section configured to execute non-linear signal processing on a collected sound signal collected by a microphone;
• and
• a transmission section configured to transmit, to the information processing apparatus, both a pre-execution sound signal before the non-linear signal processing is executed and a post-execution sound signal after the non-linear signal processing is executed;
• wherein the signal processing section is configured to execute, with first contents, the non-linear signal processing on the collected sound signal when an operation input signal is received by the signal processing section, and configured to execute, with second contents, the non-linear signal processing on the collected sound signal when the operation input signal is not received by the signal processing section,
• wherein the operation input signal is generated by an operation input to the sound signal processing apparatus by a user of the sound signal processing apparatus, the operation input causing an audible input sound collected by the microphone, and
• wherein the signal processing section is configured to receive information for identifying which operation button among a plurality of operation buttons has been operated, and execute the non-linear processing with contents that vary depending on the identified operation button.

An information processing apparatus configured to be communicatively connected to a sound signal processing apparatus, the information processing apparatus comprising:

• a reception section configured to receive, from the sound signal processing apparatus, both a pre-execution sound signal before non-linear signal processing is executed on a collected sound signal collected by a microphone and a post-execution sound signal after the non-linear signal processing is executed on the collected sound signal;
• and
• a processing section configured to execute first processing on the pre-execution sound signal and execute second processing on the post-execution sound signal, the second processing being different from the first processing;
• wherein the signal processing section is configured to execute the non-linear signal processing on the collected sound signal when an operation input signal is received by the signal processing section, and configured to not execute the non-linear signal processing on the collected sound signal when the operation input signal is not received by the signal processing section;
• wherein the operation input signal is generated by an operation input to the sound signal processing apparatus by a user of the sound signal processing apparatus, the operation input causing an audible input sound collected by the microphone;
• and
• wherein the signal processing includes receiving information for identifying which operation button among a plurality of operation buttons has been operated, and execute the non-linear processing with contents that vary depending on the identified operation button.

A sound signal processing method comprising:

• and
• transmitting, to an information processing apparatus, both a pre-execution sound signal before the non-linear signal processing is executed and a post-execution sound signal after the non-linear signal processing is executed;
• wherein the signal processing section is configured to execute, with first contents, the non-linear signal processing on the collected sound signal when an operation input signal is received by the signal processing section, and configured to execute, with second contents, the non-linear signal processing on the collected sound signal when the operation input signal is not received by the signal processing section;
• wherein the operation input signal is generated by an operation input to the sound signal processing apparatus by a user of the sound signal processing apparatus, the operation input causing an audible input sound collected by the microphone;
• and
• wherein the signal processing includes receiving information for identifying which operation button among a plurality of operation buttons has been operated, and execute the non-linear processing with contents that vary depending on the identified operation button.
