Frequently asked questions
Does Sonix support Brazilian Portuguese well?
Sonix supports 40+ languages including Portuguese, but it is a language-agnostic solution (generic multilingual model). For languages with less training volume like PT-BR, accuracy sits at 82-88%. VoxScriber uses AssemblyAI, which trained specifically on large volumes of Brazilian speech — resulting in 94-97% accuracy.
Sonix charges per hour — how does it compare to VoxScriber?
Sonix: $10/hour (pay-per-use) or $22/month for 5 hours (= $4.40/hour). VoxScriber monthly plans offer significantly more hours at a lower per-hour cost. For regular use, a monthly VoxScriber plan is 7-8x more cost-effective than Sonix pay-per-use.

VoxScriber on higher plans includes sentiment analysis and automatic summary via AssemblyAI. On the Advanced plan you have transcription + speaker identification. On the Professional plan you get all features including sentiment analysis and entity detection.
