Abstract
A system and method are provided for detecting acoustic echo in a telecommunications transmission. Detected acoustic echo is analyzed to determine if the acoustic echo includes characteristics indicative of use of a speakerphone by a remote party. Specific characteristics analyzed include the presence of multiple bulk delay values, echo magnitude, and the length of time for echo delays present within the telecommunications system. If the detected acoustic echo falls outside the range of acceptable parameters, or otherwise exceeds threshold limits, a warning signal is transmitted to the user indicating a high likelihood that the remote party is using a speakerphone. Warning the user of speakerphone use by the remote party can be helpful in ensuring that the communications between the parties is maintained in confidence.
