At 480 minutes/month, the Free tier provides 5,760 minutes/year (96 hours) of ongoing transcription. For teams processing more than 8 hours/month, the Pro tier at $0.004/min is cost-effective. For larger free testing budgets, Deepgram's $200 credit (~433 hours one-time) is more generous upfront.

Yes, Speechmatics charges for the full duration of submitted audio files, including silence, music, and non-speech segments, based on audio file length. However, Speechmatics bills per-second (not per-minute or per-hour), so a 37-second audio file costs exactly 37 seconds worth (37 × $0.004/min ÷ 60 = $0.00247) with no rounding up to a full minute. To minimize costs, preprocess audio to remove long silences using voice activity detection (VAD) or FFmpeg before sending to Speechmatics' API, especially if you frequently process audio with extended silence periods.

Speechmatics operates on a usage-based billing model for Pro tier with no subscriptions or advance payments, so there are no refunds -- you are billed only for audio processed beyond the 480 free minutes/month. The Free tier includes 480 minutes/month that resets monthly with no charges. Enterprise customers with prepaid annual commitments should negotiate refund terms directly in their contracts, as prepaid credits may expire annually and are typically non-refundable for unused balances. If you encounter a service issue or are overcharged due to a bug, contact Speechmatics support to request a credit adjustment.

Yes, Speechmatics offers a recurring free tier with 480 minutes/month (8 hours/month) of speech-to-text and 1 million characters/month of text-to-speech (English only) that resets monthly. This provides 5,760 minutes/year (96 hours) of ongoing transcription at no cost, making it the best free tier for sustained low-volume usage compared to competitors. Deepgram's $200 credit (~433 hours) is more generous upfront but does not refresh. AssemblyAI's $50 credit (~185 hours) is one-time. For teams processing under 8 hours/month long-term, Speechmatics Free tier is the most cost-effective option. For production workloads exceeding 8 hours/month, Pro tier at $0.004/min is competitive.
