Methodology

Plain rules, shown openly.

Prices come from each vendor's public pricing page, linked per row with the date checked.
Hourly prices ÷ 60. TTS assumes 750 characters per minute of agent speech. EUR treated ≈ USD (unadjusted).
Platform figures are the listed per-minute rate; most exclude STT/LLM/TTS/telephony unless stated.
Language support = listed in the vendor's official language/model table (method + confidence shown per provider). Unknowns are shown as “—”, never guessed.
