# Multilingual TEDx (Portuguese speech and transcripts) |
|
|
|
**NOTE:** This dataset contains only the Portuguese portion of the mTEDx dataset, already processed and segmented into parts. |
|
|
|
**Multilingual TEDx (mTEDx)** 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](https://www.ted.com/watch/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. |
|
Each .tgz file contains two directories: data and docs. docs contains a README detailing the files provided in data and their structure. |
|
Test sets for all [IWSLT 2021](https://iwslt.org/2021/multilingual) language pairs can be found in mtedx_iwslt2021.tgz. |
|
