We have already introduced the components of speech through a <a href=\"https:\/\/speechneurolab.ca\/en\/parole-et-trompette\/\">trumpet analogy<\/a>; today we describe the analyzes we perform to study voice and speech!<\/strong><\/p><p style=\"font-weight: 400;\">To assess spoken language, we record people when they speak. Depending on the specific research question, these recordings can take several forms:<\/p><ul><li>Sustained vowel production (for voice analysis);<\/li><li>Production of syllable sequences (mainly for the analysis of articulation and speech rate, but also voice and <a href=\"https:\/\/speechneurolab.ca\/en\/difference-between-speech-language-and-communication\/\">resonance<\/a>);<\/li><li>Repetition of syllables or words presented via headphones (for the analysis of articulation, lexical access, and phonological processing);<\/li><li>Generation of words from a letter or an image (for the analysis of articulation, lexical access, and phonological or semantic processing);<\/li><li>Text reading (mainly for articulation analysis, but also voice and resonance);<\/li><li>Narration of a personal story (mainly for the analysis of articulation, speech rate and prosody, but also voice and resonance measurements, as well as the analysis of word choice, word complexity and sentence structure and multiple measures of discourse quality and efficiency).<\/li><\/ul><p style=\"font-weight: 400;\">The preparation for the analyses begins during the participant\u2019s visit to the lab. Regardless of the type of recording that we make, we must make sure that a good quality signal is picked up by the microphone, that it is loud enough, but not too loud, that there is no background noise nor crackling and that the sampling rate is high (typically 44,000\u00a0Hz, that is, 44,000 measurements per second). To ensure that the position of the microphone remains constant throughout the recording, we use headset microphones. The recordings are made in our large soundproof room (figure 1), which allows us to obtain high-quality recordings without background noise.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3bbb349 elementor-widget elementor-widget-image\" data-id=\"3bbb349\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"2560\" height=\"1920\" src=\"https:\/\/speechneurolab.ca\/wp-content\/uploads\/2023\/04\/salle_insonorisee_in_2023-scaled.jpg\" class=\"attachment-full size-full wp-image-6452\" alt=\"\" srcset=\"https:\/\/speechneurolab.ca\/wp-content\/uploads\/2023\/04\/salle_insonorisee_in_2023-scaled.jpg 2560w, https:\/\/speechneurolab.ca\/wp-content\/uploads\/2023\/04\/salle_insonorisee_in_2023-300x225.jpg 300w, https:\/\/speechneurolab.ca\/wp-content\/uploads\/2023\/04\/salle_insonorisee_in_2023-1024x768.jpg 1024w, https:\/\/speechneurolab.ca\/wp-content\/uploads\/2023\/04\/salle_insonorisee_in_2023-768x576.jpg 768w, https:\/\/speechneurolab.ca\/wp-content\/uploads\/2023\/04\/salle_insonorisee_in_2023-1536x1152.jpg 1536w, https:\/\/speechneurolab.ca\/wp-content\/uploads\/2023\/04\/salle_insonorisee_in_2023-2048x1536.jpg 2048w, https:\/\/speechneurolab.ca\/wp-content\/uploads\/2023\/04\/salle_insonorisee_in_2023-540x405.jpg 540w, https:\/\/speechneurolab.ca\/wp-content\/uploads\/2023\/04\/salle_insonorisee_in_2023-860x645.jpg 860w, https:\/\/speechneurolab.ca\/wp-content\/uploads\/2023\/04\/salle_insonorisee_in_2023-1170x878.jpg 1170w\" sizes=\"(max-width: 2560px) 100vw, 2560px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3e64cbd elementor-widget elementor-widget-text-editor\" data-id=\"3e64cbd\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><strong>Figure 1.\u00a0<\/strong><span lang=\"EN\">Our soundproof room.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-44b5ed2 elementor-widget elementor-widget-text-editor\" data-id=\"44b5ed2\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p style=\"font-weight: 400;\">After collecting data, the analyses are conducted in the computer room.

This step is performed by at least two people who will independently determine, using an analysis grid, the type of error for each incorrect sound. Is it an inversion of phonemes, as in \u201cmaraconi\u201d instead of \u201cmacaroni\u201d? Or the insertion of additional sound? As in \u201cflish\u201d instead of \u201cfish\u201d? Or a simplification? As in \u201cumbella\u201d instead of \u201cumbrella\u201d?<\/p><p style=\"font-weight: 400;\">The analysis of speech also includes the measurement of <strong>speech rate<\/strong>, which represents the number of syllables or words produced per second as well as the coefficient of variation (which quantifies the regularity of speech rate over time). Additional metrics include the duration of vowels and\/or consonants, as well as the duration of silences, which provides further information about the speech rate.<\/p><p style=\"font-weight: 400;\">In several projects, we also calculate <strong>response time<\/strong>, that is, the time a person takes to initiate the production of a syllable or a word. This tells us about the preparation time required. The more complex or rare the item is, the longer the response time. For example, it takes longer to prepare the word \u201cwheelbarrow\u201d than the word \u201ctable\u201d, because table is simpler and more frequent. Depending on the nature of the task, response time will tell us about articulatory preparation, lexical selection , or other processes at play.<\/p><p style=\"font-weight: 400;\"><strong><u>6- Phonetic analysis<\/u><\/strong><\/p><p style=\"font-weight: 400;\">The final step is <strong>phonetic analysis<\/strong>, i.e., the analysis of the acoustic realization of consonants and\/or vowels. For example, the analysis of the spectral composition of vowels, the time it takes for the vibration of the vocal cords to be visible and many other characteristics. This information is extracted with scripts and verified manually. These analyses document the articulatory difficulties of the speakers (if any) as well as their idiosyncrasies. To develop the best possible phonetic analyses, we regularly collaborate with phoneticians: <a href=\"https:\/\/www.flsh.ulaval.ca\/notre-faculte\/repertoire-du-personnel\/johanna-pascale-roy\">Johanna-Pascale Roy<\/a> at Universit\u00e9 Laval, and <a href=\"https:\/\/www.researchgate.net\/profile\/Anna-Marczyk-2\">Anna Marczyk<\/a> from the Universit\u00e9 de Toulouse in France.<\/p><p style=\"font-weight: 400;\">In short, the analysis of spoken language is detailed, meticulous, and time-consuming!
