Understanding Finnish GSM 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 GSM 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 GSM file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Finnish GSM file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from GSM, 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 GSM file play on my computer?
GSM is a telephony codec that many consumer media players do not decode by default. Players such as VLC can open it, or you can convert the file to WAV or MP3 for broader compatibility.
Is telephone-quality GSM audio suitable for transcription?
GSM was designed specifically for human speech at an 8 kHz sample rate, so clear voice recordings generally transcribe well. As with any phone recording, heavy background noise or overlapping speakers reduces clarity.
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.
