Our products

Customisable Speech Engine

Our highly accurate speech engines can be customised to match your industry.

We offer engines for Dutch (broadcast and telephone) and English (broadcast and telephone). Our software runs as a SAAS solution but also works as an on-premises solution.


Our engines can be trained to detect specific words that are relevant for your industry.


We translate speech in less than half the duration of the audio.

Speaker Distinction

Our engines can detect how many speakers are taking part in a conversation and determine who is saying what.

Detect phrases

For compliance purposes, companies often need to understand whether or not certain phrases are mentioned during a phone call. Our software can automatically detect whether [or: when?] these phrases occur.

Customer Engagement Analytics

We believe that bringing down speech to text is only the first step.

The real value comes in distilling topics and sentiments into plain text. Therefore we deliver a complete solution that can not only translate speech but also label it automatically and make it useable for advanced analysis.


Topic - and sentiment detection

Our engines can automatically classify topics and sentiments. Using both supervised and unsupervised learning, we can help you automatically distill what your texts or calls are about.

Analyze other (unstructured) data sources

Our software package can be easily combined with unstructured data sources like email-, chat- and social media data. Combining all these sources gives you an excellent overview of what your customers talk about in different channels.

Instant Analysis

Our solution comes with an easy-to-use analytics platform that allows everybody to quickly analyze different sets of unstructured data and create neat data visualizations.
