Record announcements for Teletypewriter device (TTY) callers in the same way as you record voice announcements. However, instead of recording from the handset of your telephone, you record from a TTY device. You can use an acoustic coupler into which you place the telephone handset to attach the device to your telephone, or plug the TTY device directly into the back of a digital telephone. After you call the announcement extension, and press 1 to record, you type the announcement into the TTY device.

If you use an acoustic coupler to connect your telephone for recording, you can record TTY and voice into a single announcement. In this case, after you press 1 to record, you can type the TTY message, and then immediately pick up the handset to record the voice message. For this type of recording, digital telephones also offer the option to press # to complete the recording, which eliminates any extraneous noise at the end of the recording. Unfortunately, this method for combined TTY and voice recordings is to create extraneous noise in the middle of your announcements.

An efficient alternative to record with your telephone is to create .wav files on other recording applications, such as a PC, and then copy and save the .wav files to your announcement source. In this case, the announcement files must meet the same criteria as voice recordings. See Announcement file format requirements for more information.
