How is voice quality measured?
Measuring with MOS (Mean Opinion Score) The Mean Opinion Score, usually referred to as MOS Score, has been the most commonly-used metric to measure the overall voice call quality for decades.
What is the measurement of voice?
Vocal Intensity can be measured in decibels (dB) better known as the sound pressure level (SPL), which indicates the strength of vocal fold vibration.
How do you define voice quality?
voice quality is that component of speech which gives the primary distinction to a given speaker’s voice when pitch and loudness are excluded. It involves both phonatory and resonatory characteristics. Some of the descriptions of voice quality are harshness, breathiness and nasality.
What does Pesq measure?
The PESQ Algorithm is designed to predict subjective opinion scores of a degraded audio sample. PESQ returns a score from 4.5 to -0.5, with higher scores indicating better quality. PESQ is designed to analyze specific parameters of audio, including time warping, variable delays, transcoding, and noise.
What are the types of voice quality?
Linguists have traditionally broken the voicing continuum into five basic categories based on roles they play in a language’s phonology: (spread) voiceless, breathy, modal, creaky, (constricted) voiceless.
What are the 10 vocal qualities?

What is a good PESQ score?
-0.5 to 4.5
After the PESQ analysis, a score is given ranging from -0.5 to 4.5. A higher score means a better speech quality.
What is Mos LQO?
The mapping function, defined in [3], converts raw PESQ scores (which lie in the range -0.5 to 4.5) onto the MOS-LQO (Mean Opinion Score – Listening Quality Objective [2]) scale in the range 1 to 5. Mean opinion score (MOS) terminology. Recommendation P. 800.1, July 2006.
