Definitions
- the present invention relates, in general, to improved IP-based communication and, particularly, to a system and method for providing speech-generated text to IP-based telephone communication.
- VoIP voice over Internet Protocol
- PC personal computer
- CU-SeeMe software by White Pine and software by Vocaltech and Microsoft
- CU-SeeMe software by White Pine and software by Vocaltech and Microsoft
- Such systems typically include a microphone, a speaker and a PC plug-in sound card for providing audio data to a user's PC, and a video camera and a PC plug-in video capture card for providing video data thereto .
- the audio and video data generated in one PC is packetized and transported over the Internet for display on the other PC, such as within a browser framework.
- IP -based telephone systems having video communication capability typically allow a PC user to communicate text to the other PC user in communication therewith.
- Text entered via the keyboard of a first PC may be transported with the audio and video data over the Internet and displayed as text in a browser window on another PC in communication with the first PC.
- IP -based telephone systems are not without shortcomings. For instance, VoIP usually provides a markedly reduced quality of service relative to conventional long distance telephone services. Poorer voice quality, intermittent fading, and other interruptions are commonly encountered, especially during international calls. In response to periods of reduced quality of service, callers utilizing IP-based telephone systems frustratingly resort to communicating with typed text instead of attempting to communicate with voice. To further compound the problem, typed text data is transported at a slower rate than voice data. As a result, it is oftentimes quite difficult to engage in communication when one caller is providing voice data and the other caller is providing typed text data, due to the data transmission of voice and typed text being out of synch.
- IP -based telephone systems having video communication capabilities, having to communicate with typed text during periods of reduced quality of voice communication may result in a relatively inexperienced typist being forced to look away from the video display when entering text, thereby reducing the value in being provided a real-time video display of the other caller.
- IP-based telephone system which addresses the inherent problems associated with VoIP telephone communication.
- Another object of the present invention is to provide an IP-based telephone system which allows a caller to view received video data while concurrently transmitting video and speech-generated data.
- the present invention overcomes the shortcomings in the above-identified systems and satisfies a significant need for an IP-based telephone system having enhanced and easily utilized communication features.
- an improved IP-based telephone system includes a combination of hardware, software and/or firmware employed in association with a conventional PC in order to perform VoIP communication.
- a video capture card communicatively connected to a PC preferably receives video input data from a video source as well as from a VoIP transmission.
- a sound card communicatively connected to the PC preferably receives audio input from a microphone as well as from a VoIP transmission.
- a speech recognition device operatively associated with the PC preferably receives the microphone audio data, recognizes speech patterns therein and generates text data representing the recognized speech patterns. The generated text data is included with the microphone-provided audio data and the video camera-generated video data for transport over the Internet to another PC . In this way, a PC user may communicate video, voice and voice-generated text data to another PC user.
- the present system preferably further includes an application which receives VoIP video data and speech-generated text data which were transmitted by another PC .
- the application preferably displays the video data and produces audible signals from the audio/voice data using a speaker.
