Otherwise it automatically creates a new converted audio file. SPPAS verifies if the audio file is 16 bits sample rate and 16000 Hz frame rate. Only mono audio files are supported by automatic annotations of SPPAS. Only wav and au audio file formats are supported by Python, so does SPPAS SPPAS performs automatic annotations: It does not make sense to hope for miracles but you can expect good enough results that will allow you to save your precious time! And it begins by taking care of the recordingsвЂ¦ Audio files This window opens in the scope to be read by users (!) and should be saved with the annotated corpus. It includes all parameters and eventually warnings and errors that occurred during the annotation process. It contains important information about the annotations. Alignment will perform segmentation at phonemes and tokens levels, etc.ДЄt the end of each automatic annotation process, SPPAS produces a Procedure Outcome Report. The phonetization process will convert the normalized text in a grammar of pronunciations using X-SAMPA standard. Then text normalization automatic annotation will normalize the orthographic transcription. Indeed, at a first stage, the audio signal must be automatically segmented into Inter-Pausal Units (IPUs) which are sounding segments surrounded by silent pauses of more than X ms, and time-aligned on the speech signal.ДЄn orthographic transcription has to be performed manually inside the IPUs (do not expect to use an automatic speech transcription system). Annotation methodologyДЄfter the recording an audio file (see recordings recommendations), the first annotation to perform is to search for the IPUs.

Yellow boxes represent manual annotations, blue boxes represent automatic ones. This Figure must be read from top to bottom and from left to right, starting by the recordings and ending to the analysis of annotated files. Obviously, there are other ways to construct a corpus but 1/ do not blame SPPAS if you donвЂ™t get the results you expected, and 2/ do not contact the author if you have chosen to not follow these recommendations. It describes each step of the annotation workflow. The kind of process to implement in the perspective of obtaining rich and broad-coverage multimodal/multi-levels annotations of a corpus is illustrated in next Figure. THE recommended corpus construction workflow Let us first introduce what is the recommended way to annotate a corpus with SPPAS. However, this chapter is not a description on how each automatic annotation is working and what to expect about it: there are references for that in chapter 8.ДЄmong others, SPPAS is able to produce automatically annotations from a recorded speech sound and its orthographic transcription.

what are the requirements (files, tiers).
