Start Voice Processing Expert Search

Voice processing expert witness candidates typically have backgrounds and expertise in digital signal processing, electrical engineering, software engineering, computer science, voice identification, linguistics, natural language processing, and have specialized knowledge in speech processing. Law firm clients call on Cahn Litigation Services to locate expert witnesses to support voice processing matters, on behalf of either a plaintiff or defendant.

Voice processing, or speech processing, is the computerized handling of voice, and encompasses acquisition, manipulation, storage, voice response, voice recognition and text to speech technologies.

Often, matters requiring voice processing expert witness services involve intellectual property, such as patent infringement litigation or a trade secret dispute in a district or federal court, an Inter Partes Review (IPR) in the PTAB, or a patent case or proceeding in the International Trade Commission (ITC).

Litigation support by a voice processing expert witness could include audio recording analysis, deposition testimony, an expert report, expert opinion, and expert witness testimony in court. In a high-profile case, or litigation involving a significant financial stake, a law firm may request an expert with prior expert testimony experience. A voice processing expert needs to not only have substantive expertise but must also possess the ability to explain expert evidence to a jury and judge.
