Please select the files to be analyzed:

? Background information for the speaker to be analyzed is optional and will be used to generate the header for the output file. x Speaker information:
  • male female *

  • Philadelphia vowel system
  • *


  • ? If true, then vowels in stop words are not measured. A basic list of stop words including prepositions and other function words (the words most likely to have reduced vowels) is included in FAVE-extract. Alternatively, a list of stop words can be specified in a file uploaded by the user. x removeStopWords:
    • True
    • False
  • ? If false, then vowels marked with 0 stress in the pronouncing dictionary are not measured. If true, then all vowels are measured. x measureUnstressed:
    • True
    • False
  • ? Any vowel with a duration shorter than this value (in seconds) will not be measured. x minVowelDuration:
  • ? If 'upper', then word transcriptions are output in upper case in the output file; if 'lower', in lower case. x case:
    • upper case
    • lower case
  • ? If 'text', then the vowel formant measurements are output to a tab-delimited file. If 'plotnik', then the output is in Plotnik format (both unnormalized .plt and normalized .pll). If 'both', then both types of files are produced as output. x outputFormat:
    • text
    • plotnik
    • both
  • ? If true, then a header row is output as the first line of the text output file. If false, then no header row is output. Only applies if the outputFormat is 'text'. x outputHeader:
    • True
    • False
  • ? If 'default', then the default formant values produced by the speech analysis program (either Praat or ESPS) are used. If 'mahalanobis', then the formant prediction algorithm from Evanini (2009) is used. This algorithm compares all poles and bandwidths returned by the LPC analysis for the vowel to a distribution of expected formant poles and bandwidths taken from the ANAE measurements. x formantPredictionMethod:
    • default
    • Mahalanobis
  • ? This parameter determines at which point within the vowel the formant measurements are taken.
    'third' measures the vowel formants at one third of the vowel's duration.
    'mid' measures at the vowel's midpoint, and 'fourth' at one fourth of the vowel's duration.
    'lennig' uses the algorithm from Lennig (1978) to find a steady state within the vowel.
    'anae' uses the guidelines from Labov, Ash & Boberg (2006), namely, to measure at an F1 maximum.
    The default method, 'faav', uses the adjustments to the 'third' method developed in the FAAV project. x
    • third
    • mid
    • fourth
    • Lennig
    • ANAE
    • FAAV
  • ? Specifies the number of formants to be returned, i.e. the order of the LPC analysis to be conducted. x nFormants:
  • ? Specifies the maximum frequency to consider for vowel formants. Praat recommends a default value of 5000 Hz for male speakers and 5500 for females. However, adjustment may be necessary on a per-speaker basis to obtain the optimal values for this parameter and nFormants. x maxFormant:
  • ? In sec, the size of the Gaussian window to be used for LPC analysis (see the Praat manual for further details). x windowSize:
  • ? The cut-off value in Hz for the application of a 6 dB/octave low-pass filter (see the Praat manual for further details). x preEmphasis:
  • ? Specifies the number of samples to be used for the smoothing of the formant tracks. The window size for the running average will be (2 * nSmoothing + 1). Default value is 12, which corresponds to a 25 ms window. x nSmoothing:
  • ? Specifies whether a second pass is performed on the data, using the speaker's own system as the base of comparison for the Mahalanobis distance. Only used if the formantPredictionMethod is 'mahalanobis'. x remeasurement:
    • True
    • False

  • ? Specify the FAVE-extract options by uploading a configuration file.
    The file must be a plain .txt file, with each line in the format option=value. See individual options for list of allowed parameter values for each option.x
