Abstract
A method for providing telephone services for the hearing-impaired includes establishing a conference call between a hearing-impaired party, a hearing party and a communication assistant. The hearing party sends a voice message to the communication assistant. The communication assistant converts the voice message into a corresponding text message and transmits the text message to the hearing-impaired party. The text message is displayed to the hearing-impaired party using a device that includes a modem. The modem outputs a synchronization tone in response to receiving the text message. The synchronization tone and other tones may then be filtered to ensure that they do not reach the communication assistant and the hearing party.
