Soniox vs Deepgram
for Swedish speech-to-text
Higher accuracy in real-world Swedish, real-time features, and in-stream translation that Deepgram can't match.
Developers choose Soniox for accuracy in Swedish speech
Swedish is spoken by 10 million people worldwide — primarily in Sweden, with speakers around the world. Soniox delivers production-ready transcription and translation for Swedish, handling regional accents, code-switching, and real-world audio conditions. Deepgram lists Swedish as supported, but benchmark results show far higher error rates compared to Soniox.
Developers often like Deepgram for getting started quickly but often have to sacrifice accuracy, streaming speed, and key features. In real-world Swedish audio, which can include accents, rapid speech, and overlapping speakers, errors increase, streaming lags, and translation isn't included. Soniox offers one API that transcribes and translates Swedish (and 60+ others) with higher accuracy and smoother real-time performance, so your app instantly works worldwide.
