Abstract

Disclosed are means and method to implement a portable and fully functional audio data recording and processing system. Voice data is received, converted to digital representations, compressed and stored in solid state memories. Predefined and user defined data categories are established to enable the operator to efficiently organize data recording and retrieval actions. Data transmission means are provided, and transcription from spoken word to textual information is supported. The use of the present invention as a documentation instrument is described. The integration of the invention with a Charge Coupled Device for recording visual information is presented.

Claims

1. A system for processing audio signals containing documentary information for automatic transcription into textual documentary records, comprising:

a first means for recording audio data notations containing said documentary information in a portable electronic device;

a second means for designating the relevance of each of the recorded audio data notations according to a specific predesignated documentary format;

a third means for automatically transcribing said audio data notations into textual information; and

a fourth means for generating a formatted textual documentary record containing said documentary information contained in said audio data notations.

2. An apparatus for processing, recording and automatically transcribing audio information into preformatted textual documentation, comprising:

(a) a microphone for translating sound energy into electrical signals;

(b) a CODEC device, electrically connected to said microphone, and generating digitized electrical signals by digitizing said electrical signals, and transmitting said digitized electrical signals to a digital signal processor;

(c) said digital signal processor generating compressed digitized electrical signals by compressing said digitized electrical signals and storing said compressed digitized electrical signals into non-volatile solid state memory; and

(d) a formatted data structure for designating the relevance of each of said compressed digitized electrical signals according to a specific predesignated documentary format; and

(e) data transmission means for communicating said compressed digitized electrical signals to a personal computer/workstation, whereby said personal computer/workstation automatically transcribes said compressed digitized electrical signals in accordance with said formatted data structure into textual documentation.
