AssemblyAI charges separately for each feature — diarization, sentiment, PII redaction, entity detection. VoxParse includes everything in two flat rates: Pro $0.39/hr or Lite $0.15/hr.
Both providers offer an entry-level tier at $0.15/hr. Here's what you actually get for that price.
At the same advertised $0.15/hr, VoxParse Lite includes diarization and PII redaction at no extra cost. AssemblyAI's Best charges $0.02/hr extra for diarization alone, making the real comparable price $0.17+/hr.
