Abstract
To provide an information processing apparatus, an information processing method, and a program capable of specifying the privacy risk for a user. The information processing apparatus includes a privacy risk specification unit that specifies privacy risk information indicating a privacy risk for a user on the basis of action information indicating an action state of the user.
Claims16
An information processing apparatus, comprising:
- a microphone configured to collect a sound signal of an environment that surrounds a user;
- and
- a central processing unit (CPU) configured to:
- separate, based on a direction of the sound signal, the sound signal into a speech signal of the user and a noise signal associated with noise that surrounds the user;
- detect an utterance state of the user based on the speech signal of the user, wherein the utterance state is one of a speaking utterance state in which speech is uttered by the user or a not-speaking utterance state in which the speech is not uttered by the user;
- specify a class of the noise based on a comparison of average power value for each frequency of the noise signal with a threshold power;
- and
- specify privacy risk information for the user based on the utterance state of the user and the class of the noise, wherein the privacy risk information indicates a privacy risk for the user.
An information processing method, comprising:
- collecting, by a microphone, a sound signal of an environment that surrounds a user:
- separating, by a processor, based on a direction of the sound signal, the sound signal into a speech signal of the user and a noise signal associated with noise that surrounds the user;
- detecting, by the processor, an utterance state of the user based on the speech signal of the user, wherein the utterance state is one of a speaking utterance state in which speech is uttered by the user or a not-speaking utterance state in which the speech is not uttered by the user;
- specifying, by the processor, a class of the noise based on a comparison of average power value for each frequency of the noise signal with a threshold power;
- and
- specifying, by the processor, privacy risk information for the user based on the utterance state of the user and the class of the noise, wherein the privacy risk information indicates a privacy risk for the user.
A non-transitory computer-readable medium having stored thereon, computer-executable instructions which, when executed by a processor, cause the processor to execute operations, the operations comprising:
- collecting a sound signal of an environment that surrounds a user;
- separating, based on a direction of the sound signal, the sound signal into a speech signal of the user and a noise signal associated with noise that surrounds the user;
- detecting an utterance state of the user based on the speech signal of the user, wherein the utterance state is one of a speaking utterance state in which speech is uttered by the user or a not-speaking utterance state in which the speech is not uttered by the user;
- specifying a class of the noise based on a comparison of average power value for each frequency of the noise signal with a threshold power;
- and
- specifying privacy risk information for the user based on the utterance state of the user and the class of the noise, wherein the privacy risk information indicates a privacy risk for the user.
