Routing of sensitive-information utterances through secure channels in interactive voice sessions

A computing system comprising:

• memory;
• and
• one or more processors implemented in circuitry and communicatively coupled to the memory, the one or more processors configured to:
• obtain first audio data representing one or more initial utterances during an interactive voice session with an interactive voice system and that interacts with a server to obtain content to provide to a user during the interactive voice session, wherein the computing system is a first computing system, the interactive voice system is configured to execute on a second computing system and the server is configured to execute on a third computing system;
• transmit the first audio data to the interactive voice system via a first communication channel;
• generate, based on the first audio data, a prediction that a second audio data representing a subsequent utterance of the user in the interactive voice session will contain sensitive information, wherein the subsequent utterance follows the one or more initial utterances in time;
• upon obtaining the second audio data that includes the sensitive information:
• transmit third audio data to the interactive voice system via the first communication channel in place of the second audio data, wherein the third audio represents data that replaces the sensitive information;
• and
• transmit, the second audio data to the server via a second communication channel that bypasses the interactive voice system.

One or more non-transitory computer-readable storage media including instructions that, when executed by the one or more processors, cause the one or more processors of a first computing system to:

• obtain first audio data representing one or more initial utterances during an interactive voice session with an interactive voice system that interacts with a server to obtain content to provide to a user during the interactive voice session, wherein the interactive voice system is configured to execute on a second computing system and the server is configured to execute on a third computing system;
• transmit the first audio data to the interactive voice system via a first communication channel;
• generate, based on the first audio data, a prediction that a second audio data representing a subsequent utterance of the user in the interactive voice session will contain sensitive information, wherein the subsequent utterance follows the one or more initial utterances in time;
• upon obtaining the second audio data that includes the sensitive information:
• transmit third audio data to the interactive voice system via the first communication channel in place of the second audio data, wherein the third audio data represents data that replaces the sensitive information;
• and
• transmit the second audio data to the server via a second communication channel that bypasses the interactive voice system.
