Systems and Methods for Personalized Sound Localization in a Conversation

A computing device, comprising:

• one or more processors;
• and
• data storage, wherein the data storage has stored thereon computer-executable instructions that, when executed by the one or more processors, cause the computing device to carry out functions comprising:
• receiving, by the computing device, first and second audio signals from respective first and second audio input devices, wherein the first and second audio signals correspond to speech input of a conversation between two participants;
• estimating, by the computing device and based on the first and second audio signals, a time delay in respective arrival times for the speech input at the first and second audio input devices;
• estimating, by the computing device, respective directions for two audio sources based on the estimated time delay in the respective arrival times;
• associating, based on the estimated directions of the two audio sources, respective portions of a speech-to-text transcript of the conversation with the respective participants;
• and
• displaying, by the computing device and based on the associating of the respective portions, a modified speech-to-text transcript of the conversation that labels the respective portions of the speech-to-text transcript associated with the respective participants.

An article of manufacture comprising one or more computer readable media having computer-readable instructions stored thereon that, when executed by one or more processors of a computing device, cause the computing device to carry out functions comprising:

• receiving, by the computing device, first and second audio signals from respective first and second audio input devices, wherein the first and second audio signals correspond to speech input of a conversation between two participants;
• estimating, by the computing device and based on the first and second audio signals, a time delay in respective arrival times for the speech input at the first and second audio input devices;
• estimating, by the computing device, respective directions for two audio sources based on the estimated time delay in the respective arrival times;
• associating, based on the estimated directions of the two audio sources, respective portions of a speech-to-text transcript of the conversation with the respective participants;
• and
• displaying, by the computing device and based on the associating of the respective portions, a modified speech-to-text transcript of the conversation that labels the respective portions of the speech-to-text transcript associated with the respective participants.
