Voice Clarity
Establish individuality with your voice.
Record and replay speech signals.

Practice pitch and analyse with the fundamental frequency.

Save speech patterns to practice clear speech. 

Check vowel quality (sound frequency of formants).



  1. Record dialogue segments of your speech and stop.

  2. Click the screen to use the green line as a guide to the starting point in playing the recording. 

  3. Inspect spectrogram for the first dark band (first formant; set of adjacent harmonics at the base of the graph from a boost in resonance).

  4. Examine the mean fundamental frequency.

  5. Peak pick (highest point) fundamental frequency to determine the pitch.

  6. Practice delivering a voice with warmth and clarity.

  7. Look for phonetic stress marks to practice higher and lower pitches of vowel sounds.

  8. Analyse rhythm for a consistent harmonising pattern in English speech.


Frequency and Fundamental frequency 

Vibration and Resonance averages ("Voice depends on vocal fold vibration and resonance", n.d.)

Men: 110 - 155 Hz (lower pitch)

Women: 180 to 220 Hz (medium pitch)


For warmth and truthful voices

  • Men: 100 – 200 Hz.

  • Women:  up to 300 Hz.


Approximate lowest resonance frequency is fundamental frequency (Siupsinskiene & Lycke, 2011)

  • Men: 85 to 180 Hz  

  • Women:  165 to 255 Hz





Higher pitch 


Use a rise to a higher pitch with open questions, closed questions or closed sentences (Collins & Mees, 2003).

Joyful pitch with indignation at beginning of sentence and end of the sentence will facilitate audience comprehension (Mozziconacci & Hermes 1999). 


Theses higher pitches improve clarity in the English language.


Higher pitches range in fundamental frequency contours.



Indignation                           (fₒ)  150 - 315 Hz 

Joy                                         (fₒ)  150 - 250 Hz


Joy, happiness and confidence emotions influence pitch and should be used when clarifying information and emphasising a concept to make the experience more memorable (Dunn & Schweitzer 2005).


Lower pitch 


Use a fall in intonation pattern with statements or commands (Collins & Mees 2003).


Vowel sounds

- long repeated segment "the period" (low repetition frequency) has a low pitch,

- short repeated segment  (high repetition frequency) has a high pitch (Schnupp, Nelken & King, 2011).

The higher the vowel, the lower the first formant.
High [i]~[u]                           ( F1 )   280 ~ 310   Hz    (fee) - (foot)
Mid-high [I]~[U]                   ( F1 )   400 ~ 450  Hz    (fit) - (boot)
Mid-low [ɛ]~[ɔ ]                   ( F1 )  550 ~ 590   Hz   (fate) - (saw)
Low [æ]~[ a]                         ( F1 )  690 ~ 710       (cat) - (father)
Listen to the vowel sounds


Approximate formant frequencies in American English vowels (Carr, Durand & Ewen, 2005: University of Arizona, 2004)



Rhythm and Pausing


Use to plan longer stretches of speech for better fluency (Paradis, 2009).

Deliver a voice with more warmth by pausing.

Reach for clearer pitches by focusing on truthful thoughts (Ekman, O'Sullivan, Friesen and Scherer, 1991).

Present a read speech more clearly for the audience with pauses to give the audience time for cognitive acceptance.

For international presentations deliver the speech at approximately 100 words per minute (Gerver 1969, Seleskovitch 1978 and Lederer 1981; as cited in Chang 2005. p6.).

Establish a rhythm for listeners to process auditory input efficiently (seen on spectrogram with regularities in duration, peaks, phonological vowel sounds. syllable quantity and quality (Steiner, 2004).





Voice loudness 


The mean most comfortable listening level (MCL) is 42.7 (dB)  decibels Hearing Level (Franklin, Thelin, Nabelek and Burchfield, 2006).

An online tool by SiSoftware enables decibel to amplitude conversion if needed.


Louder voices can enhance activation states of formality, indignant, interest, stress and happiness.

Softer voices enhance activation states of apology, boredom, intimacy, relaxation and sadness (Gussenhoven, 2002).
