Abstract
Provided is a signal processing apparatus, signal processing method, and program capable of detecting an utterance by a wearer even in a state where sound is output from a vibration reproduction apparatus. A signal processing apparatus including a processing unit that operates corresponding to a vibration reproduction apparatus including a vibration reproduction unit that reproduces vibration and a vibration sensor that detects vibration, and performs processing of making it difficult to detect an utterance in utterance detection processing of detecting an utterance by a wearer of the vibration reproduction apparatus on the basis of the vibration sensor signal.
Claims17
A signal processing apparatus, comprising:
- a processing unit configured to:
- operate corresponding to a vibration reproduction apparatus, wherein the vibration reproduction apparatus includes:
- a vibration reproduction unit that reproduces vibration, and
- a vibration sensor that:
- senses displacement in a position of a member inside the vibration sensor,
- senses the vibration corresponding to the sensed displacement to generate a vibration sensor signal, and
- outputs the vibration sensor signal to the signal processing apparatus;
- execute a process to increase difficulty level of detection of an utterance in an utterance detection process, wherein
- the process is executed based on a reproduction signal to reproduce the vibration from the vibration reproduction unit,
- the utterance detection process corresponds to the detection of the utterance by a wearer of the vibration reproduction apparatus, and
- the utterance is detected based on a basis of the vibration sensor signal;
- and
- adjust a specific threshold value that judges based on a magnitude of the reproduction signal, the detection of the utterance by the wearer.
A signal processing method, comprising:
- operating corresponding to a vibration reproduction apparatus, wherein the vibration reproduction apparatus includes:

- the utterance detection process corresponds to the detection of the utterance by a wearer of the vibration reproduction apparatus, and
- the utterance is detected based on the vibration sensor signal;
- and
- adjusting a specific threshold value that judges, based on a magnitude of the reproduction signal, the detection of the utterance by the wearer.
A non-transitory computer-readable medium having stored thereon, computer-executable instructions which, when executed by a computer, cause the computer to execute operations, the operations comprising:
- operating corresponding to a vibration reproduction apparatus, wherein the vibration reproduction apparatus includes:
- a vibration reproduction unit that reproduces vibration, and
- a vibration sensor that:
- senses displacement in a position of a member inside the vibration sensor,
- senses the vibration corresponding to the sensed displacement to generate a vibration sensor signal, and
- outputs the vibration sensor signal to a signal processing apparatus;
- executing a process to increase difficulty level of detection of an utterance in utterance detection process, wherein
