Everything to built an ASR for Wolof (standard) ## Wolof Data collected by Elodie Gauthier & Pascal Uriel Elingui ### Prepared by Elodie Gauthier & Laurent Besacier #### GETALP LIG, Grenoble, France & Voxygen SAS, Dakar, Sénégal #### OVERVIEW The package contains Wolof speech corpus with audio data in the directory *data/*. The data directory contains 6 subdirectories: 1. **train** - speech data and transcription for training automatic speech recognition system (Kaldi ASR format 1 ) 2. **dev** - speech data and transcription (verified) to evaluate the ASR system (Kaldi ASR format) 3. **test** - speech data and transcription (verified) for testing the ASR system (Kaldi ASR format) 4. **dev_unverified** - original speech data and transcription (NOT verified, contains mispronunciations) 5. **test_unverified** - original speech data and transcription (NOT verified, contains mispronunciations) 6. **local** - for now, contains the Wolof vocabulary (one without vowel length contrast, and another one containing vowel length contrasted units). Once you will ran the *run.sh* script it will contain the *dict/* and *lang/* directories needed to build the ASR system. *LM/* directory contains 2 text corpus, the language model and its perplexity computed from the *dev* and *test* datasets. #### PUBLICATION ON WOLOF SPEECH & LM DATA More details on the corpus and how it was collected can be found on the following publication (please cite this bibtex if you use this data). @inproceedings{gauthier2016collecting, title={Collecting resources in sub-saharan african languages for automatic speech recognition: a case study of wolof}, author={Gauthier, Elodie and Besacier, Laurent and Voisin, Sylvie and Melese, Michael and Elingui, Uriel Pascal}, year={2016}, organization={LREC}} ### SCRIPTS In *kaldi-scripts/* you will find: * **00_init_paths.sh** - it initializes your PATH variable (required to run the Kaldi scripts) * **01_init_symlink.sh** - it creates the symbolic links (required to run the Kaldi scripts) * **02_lexicon.sh* …
