Choosing characteristics of hardware-software systems for word intelligibility of speech scoring

The article is about hardware and software systems, dedicated for word intelligibility of speech scoring. Following characteristics for procedure and equipment for word intelligibility of speech scoring are reviewed: width of frequency range, which is analyzed, its´ frequency partition (bandpass filter choice), measured values´ dynamic range, measurements´ accuracy. Experiment was performed in order to determine the frequency range width required for analysis. According to experiment results optimal width of frequency range, required for correct discrete word intelligibility valuing, was chosen. Frequency range partitioning was researched. Partitioning is suggested to be rendered correspondingly to human acoustic organ sensitivity. Requirements of choice measuring equipment are suggested. Structural configuration of software and hardware systems are given, including alternative ADC mountings, uses of logarithmic preamp, analogue or software bandpass filter.
