Techniques for wake-up word recognition and related systems and methods

A method for detecting at least one designated wake-up word for at least one speech-enabled application, the method comprising:

• using at least one computer hardware processor to perform:
• receiving a first acoustic signal generated by at least one microphone at least in part as a result of receiving an utterance spoken by a first speaker;
• obtaining information indicative of the first speaker's identity;
• using the information indicative of the first speaker's identity to determine whether the utterance spoken by the first speaker includes the at least one designated wake-up word associated with the speaker's identity;
• in response to determining that the utterance spoken by the first speaker includes the at least one designated wake-up word, interacting with the first speaker;
• receiving a second acoustic signal generated by at least one second microphone at least in part as a result of receiving, concurrently with the first microphone a second utterance spoken by a second speaker;
• obtaining information indicative of the second speaker's identity;
• interpreting the second acoustic signal at least in part by determining using the information indicative of the second speaker's identity and automated speech recognition whether the second utterance spoken by the second speaker includes a second designated wake-up word for a second speech-enabled application specific to the speaker's identity;
• and
• interacting with the second speaker based, at least in part, on results of the interpreting.

At least one non-transitory computer-readable storage medium storing processor-executable instructions that, when executed by at least one computer hardware processor, cause the at least one computer hardware processor to perform a method for detecting at least one designated wake-up word for at least one speech-enabled application, the method comprising:

• receiving a first acoustic signal generated by at least one first microphone at least in part as a result of receiving an utterance spoken by a first speaker;
• obtaining information indicative of the first speaker's identity;
• using the information indicative of the first speaker's identity to determine whether the utterance spoken by the first speaker includes the at least one designated wake-up word associated with the speaker's identity;
• in response to determining that the utterance spoken by the speaker includes the at least one designated wake-up word, interacting with the speaker;
• receiving a second acoustic signal generated by at least one second microphone at least in part as a result of receiving, concurrently with the first microphone, a second utterance spoken by a second speaker;
• obtaining information indicative of the second speaker's identity;
• interpreting the second acoustic signal at least in part by determining, using the information indicative of the second speaker's identity and automated speech recognition, whether the second utterance spoken by the second speaker includes a second designated wake-up word for a second speech-enabled application specific to the speaker's identity;
• and
• interacting with the second speaker based, at least in part, on results of the interpreting.
