Abstract:
Systems, apparatus, and techniques are described to perform operations including receiving speech that includes audio signals from a talker. A fundamental frequency, unique to the talker, is extracted from the audio signals. A tone in frequency with the extracted fundamental frequency of the received speech is modulated and the modulated tone is delivered to an audio transducing device.
