Shall we make machines work for you?

Sanelius for respeak and dictation, Kirstu for search.

Sanelius is a re-speak and dictation software that lets you dictate what you would type. It transcribes your speech as you speak. The Finnish Broadcasting Company's experts use Sanelius for captioning. And why not subtitling too. You could use it to make any office work more efficient and more convenient. Sanelius works with any application on a Windows PC.

Kirstu audio and video search keeps your treasures for you. It helps you find your pearls. Just type a word and you will find where that word was spoken in your archive. When you throw your file into Kirstu, it is automatically transcribed for  you and made searchable by word. Just like that. You can concentrate on what you will do with the material.

Who are we then?

Accessibility, equal opportunity, functioning democracy, ethical and sustainable conduct and citizenship are signposts that we follow and believe in.

In re-speak captioning, we are trusted by the Finnish Broadcasting Company. Our services help captioning for the hard-of-hearing.

Ääni Company's roots are in a number of Finnish Universities. We operate and tailor our speech recognizers to our customers' needs, to their benefit.
