Customisable speech-to-text API – Tailor-made solutions

Loved by over a million customers

What we do

Integrate speech recognition capabilities into your software by using our API. You can connect to generic models or even collaborate with us to create a customized speech recognition for your specific use-case!

API Integration and costs

Do you want to gain insights into your phone conversations? Do you want to subtitle videos at scale? Or do you want to index your video-archive? We deliver the most accurate solution.

You can easily automate workflows and transcribe large quantities of audio and video by using our speech-to-text API. Our API is quite simple. It transfers audio or video files to our ASR server and returns the transcript in the desired format.

The prices for our automatic speech-recognition API are up to 10x lower than when uploading your audio and video. Our team will contact you to explain our pricing structure. Testing our API is for free.

How it works

Customized speech recognition models

We combine the world’s latest knowledge in technology, language, and science to develop customer-specific language models for distinctive use cases. We do so by exploiting existing datasets or by creating a new dataset from scratch. Our goal is to create language models that are fully tailored to the language use of your organization.

Customization

Customization improves the  speech recognition for:

Different accents

Acoustic environment

Adaptation of the vocabulary to recognize product names, special terms, abbreviations

Adaptation to domain-specific languages such as politics, healthcare, physics, tech, or other domains

Happy customers

Meet our

HVA (Amsterdam University of Applied Sciences) – Read case study.

Our research group conducts a lot of interviews. Previously, we worked with our own pool of transcribers.
I’m glad that now our interviews are all transcribed in one place, it saves a lot of time in arranging everything.

Grundl Institute – Read case study

Amberscript offers their service cheaper than the competitors, thanks to a largely automated process. Besides, the customer service is great. Usually, everything runs so smoothly that I don’t even notice anything during the whole process.

Jochen Hummel – Executive at the Grundl Institute

Company Webcast – Read case study

In cooperation with Company Webcast, the leading webcasting provider in the Netherlands, Amberscript developed a speech recognition which is specifically trained on political language. Google’s recognition simply wasn’t accurate enough for political terms, names of political parties, or legislations, which are frequently discussed in our clients’ meetings.

Patrick van der Geest – CEO
