Voice Analysis

See beyond words with voice analysis

Enhancing Research with Precise Voice Insights

Voice analysis allows you to extract information beyond linguistics. Go deep into emotion analysis and collect data related to emotion detection (angry, happy, sad, neutral), and emotional valence (arousal, dominance, and valence). Explore fundamental voice features with metrics relating to prosody, including pitch, loudness, speaking rate, and intonation. Get data regarding perceived gender and age.

How does it work?

Any video or recording with someone speaking can be processed with the Voice Analysis Module. This means that not only can you start using this for new research but you can also go back and re-analyze old data – allowing you to uncover new findings or increase the validity of your data set by adding yet another dimension of measurement.

Once the audio has been processed locally you can chose which signals to show in the timeline, allowing for quick visualization of the data.
