Cogito Offers Comprehensive Audio Annotation for NLP Models

To help models distinguish overlapping audio sources, multiple labels should be used to annotate audio data. In order to train NLP prototypes, audio annotation services provided by Cogito can be used to provide explicit information about the classes to that an audio dataset belongs.

Sound Labeling

Sound Labeling

In sound labeling, a recording is provided to the data annotators, and they need to separate and label all the relevant sounds. The sounds of a specific musical instrument or keywords can be used as examples.

Event Tracking

Audio data from training or testing cannot predict how many sound events overlap at any given moment. Event tracking simulations simulate the multisource conditions existing in everyday life, where sounds are rarely isolated sources.

Event Tracking
Speech to Text Transcription

Speech to Text Transcription

Converting speech into text is crucial for the development of NLP technology. It is necessary to label both words and sounds as they are pronounced so that text can be produced and correct punctuation.

Audio Classification

In audio analysis, recordings are listened to and classified. Based on this data, the machines distinguish between voice and sound commands. Text-to-speech systems and virtual assistants rely heavily on audio annotation.
