Abstract

Signal quality of a communication signal that is being used to communicate with a hosted speech service is detected. When poor signal quality is detected, switching logic is controlled to selectively switch to a separate communication application or component, such as a telephony component. User interface elements can be provided for user interaction, in the switching process, as well.

based on the detected signal quality, generate a user interface that

indicates a component switching operation to switch the application from using the first communication component to using a telephony communication component to communicate with the remote speech service, and

includes a user actuatable element;

receive an indication of user actuation of the user actuatable element indicating user approval of the component switching operation; and

based on the user approval, perform the component switching operation;

a signal characteristic detector configured to detect a characteristic of the communication signal indicative of signal quality; and

threshold comparison logic configured to compare the detected characteristic to a characteristic threshold to determine whether the detected characteristic meets the characteristic threshold and to generate a quality signal indicative of the comparison.

4. The computing system of claim 3 wherein the signal characteristic detector comprises:

latency detection logic configured to detect, as the characteristic of the communication signal, a latency value indicative of a latency in the communication signal between the first communication component and the remote speech service.

5. The computing system of claim 3 wherein the signal quality detection logic comprises:

signal strength measurement logic configured to measure, as the characteristic of the communication signal, a strength of the communication signal.

6. The computing system of claim 3 wherein the first communication component comprises:
