| 1. Overview | |
| Multilingual TEDx is a multilingual speech recognition and translation corpus to facilitate the training of ASR and SLT models in additional languages. The corpus comprises audio recordings and transcripts from TEDx Talks in 8 languages (Spanish, French, Portuguese, Italian, Russian, Greek, Arabic, German) with translations into up to 5 languages (English, Spanish, French, Portguese, Italian). | |
| The audio recordings are automatically aligned at the sentence level with their manual transcriptions and translations. | |
| 2. Contents | |
| - mTEDx_v1.0_XX-YY.tar.gz | |
| 21 compressed archives, one for each language pair (XX-YY) and for additional ASR data (XX-XX) | |
| 2.1 Archive Contents | |
| - data/ | |
| - docs/ | |
| 2.1.1 data/ | |
| It contains three directories, one for each set on which the corpus has been partitioned: | |
| - train | |
| the set utilized to train models | |
| - valid | |
| the set utilized for validation during training | |
| - test | |
| the set utilized to evaluate models | |
| Each data split directory is organized in three sub-directories: | |
| - txt/ | |
| it contains three or four text files: | |
| (1) the source language sentences, | |
| (2) the corresponding aligned target language sentences (if translations) | |
| (3) the source audio alignment info in yaml format, one line for each sentence | |
| (4) the source audio alignment in kaldi segments format, one line for each sentence | |
| note that the text files contain the transcripts/translations only, and do not have the segment ids on the same line. | |
| the text files are parallel line-by-line with the segments and yaml files, which contain the segment ids. | |
| - vtt/ | |
| it contains the original vtt files for each talk. | |
| - wav/ | |
| it contains the audio files in flac format, one for each TEDx talk. | |
| we distribute flac files for compression and easier download. | |
| if you need to convert between flac and wav, we recommend sox; only the file metadata will change in conversion | |
| 2.1.2 docs/ | |
