The rise of voice assistants and natural language interfaces requires perfectly structured audio databases to train oral recognition and comprehension models.
The mission
Set up a Workflow multimodal annotation to combine audio files and rich text transcripts.
To meet this objective, Innovatiana has developed a comprehensive process that includes:
- The fine segmentation of audio tracks into units of meaning (sentences, keywords);
- Manual correction of transcripts and annotation of specific elements (intentions, emotions, hesitations).
The results
- An aligned audio-text corpus, ready for training speech recognition (ASR) and language comprehension (NLU) models;
- A better ability for voice assistants to understand the nuances of human conversations;
- A reduction in the error rate in user-AI interactions.
