TELEPHONE CALLS BETWEEN THE HEARING AND THE DEAF

失聪或有言语障碍的人通常需要与 通过电话听/说世界，作为他们就业的一部分，在社会上 互动，或获取商品或服务。目前，这样 对话通常是通过“接力服务”实现的。 不幸的是，中继呼叫设置起来不方便，而且由于只有一个 人们可能会说话或打字，有时这些电话很慢，令人沮丧 对双方来说都是如此。 在一种配置中，拟议的第一阶段设备将检测 由失聪或言语受损的人接收的呼叫来自语音呼叫者， TTY、标准调制解调器或传真。当检测到语音呼叫者时，该设备 将在第二条电话线上自动呼叫并创建与 当地的转播服务。该设备将支持语音的桥接 以支持“VCO”和“HCO”，并将允许 听力/说话的人直接呼叫失聪/言语受损的人 不需要特别的指示。 研发的重点将是允许任何一方发表评论或 随时打断，这将导致更自然的对话。至 为此，数字同时语音和数据等先进技术 将采用(Dsvd)。 建议的商业应用： 拟议的研发将导致一种电信设备，它将是 适合聋人及/或有语言障碍的人士与 听/说的世界。该产品也将在继电器上销售 服务。建议工作的要素可用于标准的数字视频显示 调制解调器，并将单独销售。

Deaf or speech impaired persons often need to speak to the hearing/speaking world by telephone as part of their employment, in social interactions, or to access goods or services. Presently, such conversations are generally made possible through the "relay services". Unfortunately, relay calls are inconvenient to set up, and since only one person may speak, or type, at a time these calls are slow and frustrating for both parties. The proposed Phase I device, in one configuration, will detect whether a call received by a deaf or speech impaired person is from a voice caller, TTY, standard modem, or fax. When a voice caller is detected the device will automatically call out on a second phone line and create a link with the local relay service. The device will support bridging of voice sounds across the two phone lines to support "VCO" and "HCO", and will allow a hearing/speaking person to call a deaf/speech impaired person directly without the need for special instructions. An emphasis of the R&D will be to allow either party to comment or interrupt at any time which will lead to more natural conversations. To this end, advanced techniques such as digital simultaneous voice and data (DSVD) will be employed. PROPOSED COMMERCIAL APPLICATION: The proposed R&D will result in a telecommunications device which will be suitable for the deaf and/or speech impaired to converse with the hearing/speaking world. This product will also be marketed to the relay services. Elements of the proposed work can be used with standard DSVD modems and will be marketed separately.
