Claim:
1. A method comprising: receiving a speech signal at audio input means of a user device for transmission to a remote node in a communication session; determining, using a processor of the user device and based at least in part on activity of an echo canceller or an echo suppressor at the user device, whether the user device is operating in a first mode or a second mode, the determining comprising: determining that the user device is operating in the first mode if the activity of the echo canceller or the echo suppressor indicates that a signal strength of secondary audio signals generated by an application which is not involved with the communication session are above a threshold strength thereby indicating that the secondary audio signals are likely to disturb the speech signal received at the audio input means; and determining that the user device is operating in the second mode if the activity of the echo canceller or the echo suppressor indicates that the signal strength of the secondary audio signals generated by the application are below the threshold strength thereby indicating that the secondary audio signals are unlikely to disturb the speech signal received at the audio input means; and selectively suppressing the secondary audio signals generated by the application from being output from the user device during the communication session if it is determined that the user device is operating in the first mode, and not suppressing the secondary audio signals from being output from the user device during the communication session if it is determined that the user device is operating in the second mode.
