Understanding Finnish MTS 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 MTS 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 MTS file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Finnish MTS file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from MTS, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Finnish with Sonix:
Why won't my MTS file play on my computer?
MTS files use the AVCHD transport-stream structure, which some default media players do not support, and clips copied out of the camcorder's AVCHD folder can lose playback context. Opening the file in VLC or remuxing it to MP4 usually resolves the issue.
Do I need to convert MTS to MP4 before transcribing?
No. You can upload the MTS file directly, and its audio track is extracted and transcribed the same way as an MP4 upload.
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.
