Answer: A

The Computerized Speech Lab is used to examine audio.

The Computerized Speech Lab (CSL), made by KayPENTAX, is a hardware and software system for recording and analysing speech. Forensic laboratories use it for speaker identification, producing spectrograms and measuring formants, pitch and other acoustic features of questioned and specimen voice recordings.

Video, images and documents are examined with other tools, such as video enhancement software, image analysis systems and the video spectral comparator for documents.
