Aim of this multimedia demo<\/h3>

The aim of this multimedia demo is to illustrate the changes in voice fundamental frequency (also called ‘voice pitch’) that occur as a function of age and talker sex. The recordings are taken from two speech corpora recorded at UCL: kidLUCID<\/a> and elderLUCID. Both of these corpora are available for research purposes (see here<\/a>).<\/p>

\"figure2\"<\/a>
Change in median fundamental frequency based on data collected during \u2018spot the difference\u2019 tasks (diapix) carried out between pairs of talkers. These data have been accumulated across studies carried out with children (reported in Hazan et al., 2016) and with young and older adults (Hazan et al., 2018).<\/figcaption><\/figure>

Using the diapix task to elicit spontaneous speech in interaction<\/h3>

‘Diapix’ (van Engen et al., 2011, Baker and Hazan, 2011) is a problem-solving ‘spot the difference’ picture task used for eliciting spontaneous speech interactions between two participants. Participants have to try and work out what 12 differences there are between their pictures without seeing their partner’s picture. The pictures are carefully designed to elicit certain vocabulary items. This task has been used with children aged 8 years and above as well as with adults aged up to 85 years.\u00a0To get a ‘clean’ recording for each participant, the diapix task can be done with each participant seated in a separate sound-treated booth and communicating via headphones.<\/p>

Examples of spontaneous speech for different age groups<\/h3>

The following examples illustrate the changes in the fundamental frequency of the voice (‘voice pitch’) for female and male talkers at different ages. \u00a0They are extracted from recordings made while participants were carrying out the diapix task with their conversational partners in good listening conditions. All talkers are discussing the shack on the top right hand side of the pictures above. Median fundamental frequency (f0) values were calculated over the whole recording of the diapix task lasting 5-6 minutes on average.<\/p>

9-10\u00a0year olds<\/h4>

Note how similar f0 values are for male and female talkers at this age. It is quite difficult to reliably tell the sex of the talker from the voice.<\/p>

F39, 10 year old girl (median f0: 258 Hz)<\/p>https:\/\/darkslategrey-mongoose-524898.hostingersite.com\/wp-content\/uploads\/2016\/10\/F39_10yr_beach1_NB_shack.wav<\/a><\/audio>

M30, 10 year old boy (median f0: 271 Hz)<\/p>https:\/\/darkslategrey-mongoose-524898.hostingersite.com\/wp-content\/uploads\/2016\/10\/M30_10yr_beach1_NB_shack.wav<\/a><\/audio>

\u00a0<\/h4>

11-12 year olds<\/h4>

These two 11 year old talkers still have a high median f0.<\/p>

F46, 11 year old girl (median f0: 251 Hz)<\/p>https:\/\/darkslategrey-mongoose-524898.hostingersite.com\/wp-content\/uploads\/2016\/10\/F46_11_beach1_shack.wav<\/a><\/audio>

M17, 11 year old boy (median f0: 261 Hz)<\/p>https:\/\/darkslategrey-mongoose-524898.hostingersite.com\/wp-content\/uploads\/2016\/10\/M17_11_beach1_shack.wav<\/a><\/audio>

\u00a0<\/h4>

13-14 year olds<\/h4>

Here, you notice that the median f0 for the 13 year old girl is lower than that measured for the 9 and 11 year old girls. The first male talker, 14 year old M21, is still showing a high f0 while M07, also aged 14, \u00a0is more advanced in puberty and shows a dramatic reduction in median f0.<\/p>

F06, 13 year old girl (median f0: 214 Hz)<\/p>https:\/\/darkslategrey-mongoose-524898.hostingersite.com\/wp-content\/uploads\/2016\/10\/F6_13_beach1_shack.wav<\/a><\/audio>

M21, 14 year old boy (median f0: 216 Hz)<\/p>https:\/\/darkslategrey-mongoose-524898.hostingersite.com\/wp-content\/uploads\/2016\/10\/M21_14_beach1_shack.wav<\/a><\/audio>

M07, 14 year old boy (median f0: 85Hz)<\/p>https:\/\/darkslategrey-mongoose-524898.hostingersite.com\/wp-content\/uploads\/2016\/10\/M7_14_beach1_shack.wav<\/a><\/audio>

\u00a0<\/h4>

Young adults<\/h4>

These two young adults display typical average f0 values for their age and sex.<\/p>

YAF09, 22 year old woman (median f0: 223 Hz)<\/p>https:\/\/darkslategrey-mongoose-524898.hostingersite.com\/wp-content\/uploads\/2016\/10\/YAF09_beach1_shack.wav<\/a><\/audio>

YAM01, 23 year old man (median f0: 105 Hz)<\/p>https:\/\/darkslategrey-mongoose-524898.hostingersite.com\/wp-content\/uploads\/2016\/10\/YAM01_beach1_shack.wav<\/a><\/audio>

\u00a0<\/h4>

Older adults (65-85 yrs)<\/h4>

In this age range, the difference in perceived pitch tends to be reduced as there is a tendency for fundamental frequency to decrease in women and increase in men. In fact, the two talkers here, also chosen at random, have virtually identical mean fundamental frequency.<\/p>

OAF35, 72 year old woman (median f0: 149 Hz)<\/p>https:\/\/darkslategrey-mongoose-524898.hostingersite.com\/wp-content\/uploads\/2016\/10\/OAF35_beach1_shack.wav<\/a><\/audio>

OAM61, 69 year old man (median f0: 151 Hz)<\/p>https:\/\/darkslategrey-mongoose-524898.hostingersite.com\/wp-content\/uploads\/2016\/10\/OAM61_beach1_shack.wav<\/a><\/audio>
