![]() ![]() In runScript, the path to the external script, as well as the paths to infile, outfile and folder parameters are taken relative to the folder of the current script. You can pass values for boolean either as the quoted strings “yes” and “no” (or their variants) or as the unquoted numbers 1 and 0. The format can be "(whitespace-separated)" or "(formula)" the initial value should then be probably be something like "10 -9 80" or ", "18000 0.3" Realvector: variable$, format$, initialValue$įor a vector with real values.

You can use the following field types in your forms: real: variable$, initialValue$įor positive real numbers: the form issues an error message if the number that you enter is negative or zero (further on in the script, you can freely change it to any real number, including negatives ones such as -1.5, or zero).įor whole numbers: the form reads the number as an integer (further on in the script, you can give it any real value, e.g. Inside the script, the value “0.3 (= not too loud)” will be known as 0.3, because this is a numeric field. Note that the first letter of these variables is converted to lower case, so that you can assign to them in your script. Inside the script, the field names can be accessed as variables: these have underscores instead of spaces, and the parentheses (Hz) have been chopped off. When running this script, the interpreter puts a settings window ( form) on your screen, entitled “Play a sine wave”, with two fields, titled “Sine frequency (Hz)” and “Gain”, that have been provided with the standard values “377.0” and “0.3 (= not too loud)”, which you can change before clicking OK. The file playSine.praat may contain the following: form: "Play a sine wave" Recommendations for voice sample normalization with the PSOLA algorithm are thus to prefer shortening over lengthening and, if not possible, to limit the extent of duration manipulation-for example, by normalizing to the mean sample duration.You can cause a Praat script to prompt for arguments. In particular, there was a linear decrease in attractiveness as a function of modification percentage (especially for the word, as compared with the vowels). Duration manipulation, on the other hand, altered perceived attractiveness for the lengthening condition. Results for the effect of duration showed that the nonmanipulated sound sample duration was not predictive of perceived attractiveness. Results for the effect of stimulus type showed that word length samples were more attractive to the opposite sex than vowels. Duration manipulation was performed using the pitch synchronous overlap and add (PSOLA) algorithm implemented in Praat. These samples were presented in three conditions: nonmanipulated, shortened, and lengthened duration. Voice samples included a single vowel /a/, a three-vowel series /i a o/, and the French word "bonjour" (i.e., "hello"). Twenty-seven male and female raters made attractiveness judgments of 30 male and female voice samples. word) influence perceived voice attractiveness. The aim of this experiment was to investigate the extent to which stimulus duration (nonmanipulated vs. Moreover, the type of voice stimulus varies from a single vowel to complex sentences. Especially, the duration of voice samples is often neglected as a factor and happens to be manipulated without the perceptual consequences of these manipulations being known. Some aspects of the methodology used in this domain deserve particular attention. ![]() ![]() Voice attractiveness is a relatively new area of research. ![]()
