Abstract: The invention concerns a system (300) and method (400) for bandwidth extension of voice for improving the quality of voice in a communication system. The method and system include the steps of filtering (402) a wideband voice signal to produce a first filtered signal (301) and a second filtered signal (331), vocoding (404) the first filtered signal to produce a narrowband vocoded signal (130), compensating (406) the second filtered signal for time alignment with the narrowband vocoded signal, and adding (335) the narrowband vocoded signal with the second filtered signal to produce a wideband vocoded signal (250). One or more features from the wideband vocoded signal can be extracted to create a wideband feature vector (147) for storage in a wideband vocoded speech database (220).

Abstract: A multimedia processor system (400) for a mobile device, the system includes a central processing unit (CPU) (105), a system bus port (120) accessible by the CPU, and a virtual file system (VFS) (110) accessible by the CPU. The VFS is synchronized with a remote file system (210) of a remote application processor (200) coupled to the system bus port. The system further includes at least one storage device port (130) accessible by the CPU and at least one storage device pass-thru port (140) coupled to the at least one storage device port by a pass-thru controller (150) managed by the CPU, where the CPU instructs the pass-thru controller to disable access of the at least one pass-thru port to the at least one storage device port.

Abstract: A bandwidth efficient digital voice communication system (10) can include a speech-to-text converter (22) for converting a voice signal to a text representation, a speech parameter extractor (28) for extracting user identifiable parameters from a voice signal, and a text-to-speech converter (44) for converting the text representation and the user identifiable parameters from the voice signal in real time. The user identifiable parameters can be among pitch rate, gain, fundamental frequency, and formats. The speech-to-text converter can further include a text to phoneme segmentation module (24) providing flags to indicate a plurality of phoneme boundaries, an automatic phonetic segmentation module (26) coupled to the text to phoneme segmentation module and the speech parameter extractor, and a voice parameter manager (29) for receiving the text representation, the flags indicative of the plurality of phoneme boundaries, and the user identifiable parameters from the voice signal.

Abstract: A method and a system for performing a conference call in a network (102) are disclosed. The network (102) includes a plurality of electronic devices (104, 106, 108 110, 112, and 114) that interact with each other. The method includes receiving (302) audio streams from the plurality of electronic devices, and compiling (304) them so that the audio streams received are separate relative to each other. The method also includes transmitting (306) the audio streams to the plurality of electronic devices, and processing (308) the audio streams in at least one electronic device. The audio streams are also positioned in a virtual conference room (512), associated with at least one electronic device.

Abstract: A voice communication system and method for improved bandwidth and enhanced concatenative speech synthesis includes a transmitter (10) having a voice recognition engine (12) that receives speech and provides text, a voice segmentation module (24) that segments the speech into a plurality of speech units or snippets, a database (18) for storing the snippets, a voice parameter extractor (28) for extracting among rate or gain, and a data formatter (20) that converts text to snippets and compresses snippets. The data formatter can merge snippets and text into a data stream.

Abstract: A telecommunication device (200) adaptable for elderly users (105). The telecommunication device can include a user classifier (205) and one or more audio processors (215 and 220). The user classifier can establish one of several categories for a device user, wherein the category determines at least one configurable setting of the telecommunication device. One of the several categories indicates that a user is elderly or subjectively elderly. The audio processors can digitally processes audio streams for the telecommunication device. At least one configurable setting can adjust operations of the audio processors so that the processors operate differently for users classified as elderly than for users not classified as elderly. The audio processors can include an incoming audio processor (215) and an outgoing audio processor (220).

Abstract: Systems and methods are provided for transmitting non-voice data over a dispatch voice channel of a wireless network. A request is received from a user of a first wireless device to transfer non-voice data, and a private call request is transmitted to the wireless network. The private call request includes information indicating image transfer over dispatch voice channel mode. A call grant message is received from the wireless network and indicates a first dispatch voice channel that has been allocated to the first wireless device. The non-voice data is transmitted from the first wireless device to the second wireless device via the first dispatch voice channel. Also provided are systems and methods for temporarily interrupting the transmission of non-voice data via a dispatch voice channel so as to transmit voice data via the dispatch voice channel.

Abstract: A user who desires to establish a temporary talk group first requests a temporary group identifier, then the user specifies the talk group membership and a validity period. The temporary talk group can be set up using a mobile communication device, or by use of a computer which connects with a service provider's server over the Internet.
