1. A method for controlling transitions between a plurality of types of audio information being received via an audio stream, comprising the steps of:
- continuously storing the audio stream;
transmitting a present type of audio information from the audio stream;
detecting a new type of audio information in the audio stream at a point in time;
transmitting at an accelerated rate the new type of audio information from the stored audio stream until the detected time point is reached; and
transmitting the new type of audio information from the audio stream after the detected time point is reached in the stored audio stream.

Abstract
According to an embodiment, both a first and second of audio information are buffered during transmission so that when a transition occurs between transmission types no information is lost.

12. A method of communicating both voice and TDD information in audio information of telecommunication calls, comprising the steps of:
-
determining by a telecommunication system that both voice and TDD information may be present on an incoming telecommunication call to the telecommunication system by accessing data for an originating telecommunication unit of an incoming telecommunication call to a telecommunication system, and identifying if the originating telecommunication unit is marked as using TDD information; and providing for transitions between voice and TDD information on the telecommunication call upon the determination being made that both voice and TDD information may be present on the telecommunication call. - View Dependent Claims (13, 14)

15. A method for performing transitions between voice information and TDD information in an audio stream, comprising the steps of:
-
continuously storing the audio stream; transmitting voice information from the audio stream upon voice information having been present; detecting TDD information in the audio stream at a point in time; transmitting at an accelerated rate TDD information from the stored audio stream until the detected time point is reached; and transmitting TDD information from the audio stream after the detected time point is reached in the stored audio stream. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A processor-readable medium comprising processor-executable instructions stored in a device configured for:
-
continuously storing the audio stream; transmitting a present type of audio information from the audio stream; detecting a new type of audio information in the audio stream at a point in time; transmitting at an accelerated rate the new type of audio information from the stored audio stream until the detected time point is reached; and transmitting the new type of audio information from the audio stream after the detected time point is reached in the stored audio stream. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
