Estimate combined speech-to-text and text-to-speech cost across Whisper, Deepgram, ElevenLabs, and OpenAI TTS. Adjust volume — the estimate updates live.
Speech-to-text cost is your monthly transcription minutes multiplied by the selected provider's per-minute rate. Text-to-speech cost is your monthly synthesized character count multiplied by the selected provider's per-character rate. The two totals are billed on separate APIs and simply summed.
It doesn't account for real-time streaming surcharges, speaker diarization add-ons, custom voice cloning setup fees, or volume discounts above high usage tiers. Treat this as a directional estimate for budgeting, not an exact invoice.
Speech-to-text cost is minutes of audio transcribed per month times the provider's per-minute rate. Text-to-speech cost is characters synthesized per month times the provider's per-character rate. The two are billed independently and summed for a total.
ElevenLabs specializes in highly realistic, expressive voice cloning and emotional range, which commands a premium over OpenAI's more general-purpose TTS voices that are cheaper but less customizable.
No. STT scales with audio duration (minutes), while TTS scales with output text length (characters), so a short voice reply and a long transcription job are priced on entirely different units.
