The short version

  • Only Azure Functions has a free tier, so it costs nothing to try first.
  • Each has a real cost: Azure Functions consumption plan free grant is capped at 1 million executions and 400,000 GB-seconds of resource consumption per month per subscription, billed per GB-second beyond that; Verbit only a small self-service tier has a published price; the institutional plans that most education buyers actually need are quoted, so budgeting requires a sales cycle and comparison against competitors requires several.

Verbit

  • A university that must caption recorded teaching to meet accessibility law and wants machine output for general content with human correction only where a student accommodation appliesnot Azure Functions
  • A broadcaster needing live realtime captioning to regulatory standard, which the VITAC operation supplies rather than a pure software vendornot Azure Functions

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Azure Functions

  • Consumption plan free grant is capped at 1 million executions and 400,000 GB-seconds of resource consumption per month per subscription, billed per GB-second beyond that
  • The newer Flex Consumption plan's free grant is smaller still, at 250,000 executions and 100,000 GB-seconds per month
  • Premium plan avoids per-execution charges but bills continuously for allocated core seconds and memory regardless of invocation volume
  • Memory is rounded up to the nearest 128 MB and execution time to the nearest 1 ms for billing, so small overages round upward

Verbit

  • Only a small self-service tier has a published price; the institutional plans that most education buyers actually need are quoted, so budgeting requires a sales cycle and comparison against competitors requires several.
  • Accuracy claims are benchmarked on clean audio with standard accents, and real lecture theatre recordings with technical vocabulary and non-native speakers fall well short, so the contracted level and the audio assumptions behind it must be written into the agreement.
  • The human correction layer is what delivers the accuracy institutions buy, and it introduces turnaround times measured in hours or days, which does not suit anyone expecting transcripts immediately after a session.
  • Cost scales with hours of content, so an institution that recorded everything during remote teaching and never reduced the volume can find transcription costing more than the lecture capture platform generating the recordings.
  • Verbit has grown by acquisition and consolidated several transcription brands, and customers of acquired services have been migrated onto Verbit contracts and pricing on the acquirer's timetable rather than their own.

Answered from the vendors’ own pages

Azure Functions: Does Azure Functions have a free tier?

Yes, Azure Functions includes a monthly free grant of 1 million requests and 400,000 GB-seconds on the Consumption Plan, or 250,000 executions and 100,000 GB-seconds on Flex Consumption.

Source
Verbit: Is there published pricing?

Only for the entry Standard tier at around $24 a month for 100 hours split between live and post-production. Campus Complete and the legal and media unlimited plans are quoted.

Azure Functions: What is Azure Functions' pricing model?

Azure Functions uses usage-based pricing. Consumption plans charge per second of resource consumption and per execution, measured in gigabyte-seconds and rounded to the nearest 128 MB.

Source
Verbit: What accuracy does Verbit deliver?

Machine-only output is materially less accurate than the corrected tiers. Accuracy is a contracted service level on the human-corrected plans, and it assumes reasonable audio quality. Negotiate the figure and the remedy, not the marketing number.

Azure Functions: What is the minimum execution time for Azure Functions?

The minimum execution time is 100 milliseconds on Consumption plans. Premium plans charge based on core seconds and allocated memory.

Source
Verbit: What is VITAC?

A large North American broadcast captioning business Verbit acquired in 2021. It is why Verbit can supply live realtime captioning at broadcast standard rather than only post-production transcripts.

Verbit: Can I mix machine and human transcription?

Yes, and it is the main reason education buyers choose Verbit: route routine content through machine processing and accommodation-covered content through human correction on the same account.
