What aspect of voice assessment does the 'Max. Phonational Frequency Range' measure?

The 'Maximum Phonational Frequency Range' measures the full range of pitches a voice can produce. This assessment provides insight into both the high and low frequencies a speaker can reach, which is essential for determining vocal quality and ability.

Understanding the phonational frequency range is particularly important in voice therapy and assessment because it helps clinicians identify potential limitations in pitch range that could impact communication effectiveness. A broader frequency range typically suggests a more flexible and healthier voice, while a restricted range may indicate vocal issues that need to be addressed. This measurement is distinct from the aspects of volume or resonance, focusing specifically on the ability to produce different pitches rather than how loud or rich the voice sounds.
