The resulting, aligned phonetic transcription in the downloaded TextGrid may well contain erroneous phonetic alignments, especially at places where the speech is interrupted by interjections, laughs, jeers, etc etc. “What you see are three so-called ‘annotation layers’ (or ‘levels’ or ‘tiers’): word (ORT-MAU), standard pronunciation of the word (KAN-MAU) and phonetic segmentation (MAU, encoded in X-SAMPA).” For X-SAMPA, see wikipedia. Misalignment in the input files will result in misalignment in the output. all words in the text file must be in the audio file, and vice versa. Make sure that the contents of the input files match exactly, i.e. The audio file can be stereo or mono in any common format if necessary it will be converted to mono during the MAUS process. Use the appropriate extension for each file: DOC for formatted text, TXT for unformatted text, WAV for audio WAV files, etc. The file NAME must not contain blanks or periods or hyphens (but underscore _ is OK). Input file preparationĪs explained on the WebMAUS website, the audio file and text file to be aligned must have the exact same file name. Depending on your web browser, you may right-click on the TextGrid link, choose “Save…”, and save the TextGrid object into the same folder where you have the matching audio file (by the same name) and perhaps also the matching text file by the same name. Upload the files.Ĭhoose the appropriate language (such as English-GB for BBC recordings of Shakespeare’s plays), and choose TextGrid as output format.Īccept the terms of usage, and press the big blue button “Run Web Service” under the checkbox.Īfter a waiting time (which may be several minutes for long audio files!), one or more resulting TextGrids appear in the output panel. This document was prepared with version 3.9 of the WebMAUS service.īefore using the service, audio and text files need to be prepared, see details below.Ĭlick in the file area, and select the associated audio and text files, see details below. “This web service inputs a media file with a speech signal and a text file with a corresponding orthographic transcript, and computes a word segmentation and a phonetic segmentation and labeling.” Select the service ‘WebMAUS Basic’ from the ‘Service sidebar’ on the left-hand side of the home page The phonetic alignment is provided under the acronym “WebMAUS” by this web service. The results are collected in a TextGrid, which can be read and used further (e.g. From an end-user perspective, this amounts to (a) the synchronization of a pre-existing orthographic transcription with the speech signal, (b) expansion of the orthographic transcription to dictionary pronunciation of each word in phonetic symbols, and (c) alignment or synchronization of each speech sound symbol to the corresponding part of the audio signal. Phonetic analyses are accelerated considerably by means of so-called phonetic alignment.
