Understanding Finnish AAC files
Finnish has two broad dialect groups, Western and Eastern, but the bigger factor for speech recognition is the gap between standard written Finnish (yleiskieli) and everyday spoken Finnish (puhekieli), which shortens words and pronouns. Casual conversational recordings sound noticeably different from scripted broadcast or lecture speech.

Frequently asked questions
How to improve the accuracy of your Finnish transcripts?
Start by improving the quality of the Finnish AAC file that you upload to Sonix. Please use high quality recording equipment, recording in a quiet environment, and ensure that your speakers are speaking clearly to ensure that your transcript is as accurate as possible.
Any advice for the Finnish AAC file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Finnish AAC file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from AAC, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Finnish with Sonix:
What is the difference between AAC and M4A files?
Both typically contain the same AAC-encoded audio; the difference is packaging. A .aac file is a raw ADTS stream, while a .m4a file wraps the audio in an MPEG-4 container that supports metadata such as tags, artwork, and chapters.
Why won't my AAC file open in some apps?
Raw .aac files are a bare audio stream without a standard container, so some players and editors that expect MP4/M4A files cannot read them. Renaming the extension does not fix this — remux or convert the file into an M4A or MP3 instead.
Can Sonix transcribe colloquial spoken Finnish (puhekieli)?
Yes. Sonix transcribes the words as they are spoken, so casual recordings come back in colloquial forms, and you can standardize the spelling in the built-in editor before exporting.
Does Finnish transcription handle long compound words?
Finnish builds long compound and inflected word forms, and Sonix transcribes them as complete words. Any misrecognized rare compounds or proper nouns can be corrected in the editor.
Can Sonix create Finnish subtitles from a video?
Yes. Upload a Finnish video, transcribe it, and export the transcript as SRT or VTT subtitle files that work with most media players and video editing tools.

I absolutely loved how well the software was able to distinguish between individual speakers. Exceptional product and well-polished.
I’ve been using your transcription software for about a year now. I just wanted to let you guys know that I think it is incredible. I have tried many alternatives, and none of them have been able to match the accuracy of Sonix!
