High quality, real world speech datasets
South AfricanisiZulu Speech Datasets
This speech data collection was planned, collected, annotated and curated with natural language processing best practice in mind. Machine learning and speech recognition rely on unbiased, fully representative datasets, which is why Way With Words speech collection focuses on collecting speech data from the widest range of demographic elements and most equal split between gender distribution as possible.
Applications of NLP in AI demand that speech recognition training data be qualified, structured, and represented to suit machine learning in speech processing. We believe that we’ve collected useful baseline datasets to benchmark effective improvements in the accuracy of existing speech to text models. Speech recognition training data can also, of course, be commissioned on a bespoke basis to suit any conventions, needs, domains, and languages that may be required.
