A signal strength and readability report is a standardized format for reporting the strength of the radio signal and the readability (quality) of the radiotelephone (voice) or radiotelegraph (Morse code) signal transmitted by another station as received at the reporting station's location and by their radio station equipment. These report ...
A simple way to ensure the rating applied is useful is to rate the "O" column first based on the intelligibility of the station. If you can understand everything easily, the station will rate a 4 or higher. If you have to work hard, but can understand everything '3' is the appropriate rating.
The term baritone was developed in relation to classical and operatic voices, where the classification is based not merely on the singer's vocal range but also on the tessitura and timbre of the voice. For classical and operatic singers, their voice type determines the roles they will sing and is a primary method of categorization.
Mean opinion score (MOS) is a measure used in the domain of Quality of Experience and telecommunications engineering, representing overall quality of a stimulus or system.. It is the arithmetic mean over all individual "values on a predefined scale that a subject assigns to his opinion of the performance of a system quality".
Speech Transmission Index (STI) is a measure of speech transmission quality. The absolute measurement of speech intelligibility is a complex science. The STI measures some physical characteristics of a transmission channel (a room, electro-acoustic equipment, telephone line, etc.), and expresses the ability of the channel to carry across the characteristics of a speech signal.
NR algorithms (e.g., Recommendation ITU-T P.563 [7]) are low-accuracy estimates only, as the originating voice characteristics (e.g., male or female talker, background noise, non-voice) of the source reference is completely unknown. A common variant of NR algorithms does not even analyze the decoded audio signal, but works on an analysis of the ...
A sonority hierarchy or sonority scale is a hierarchical ranking of speech sounds (or phones). Sonority is loosely defined as the loudness of speech sounds relative to other sounds of the same pitch, length and stress, [ 1 ] therefore sonority is often related to rankings for phones to their amplitude.

These different forms of voice production are known as vocal registers. While the exact number and definition of vocal registers is a controversial topic within the field of singing, the sciences identify only four registers: the whistle register , the falsetto register , the modal register , and the vocal fry register .
