The short version

  • Only Amazon Lex has a free tier, so it costs nothing to try first.
  • Each has a real cost: Amazon Lex pay-as-you-go model with no standard free tier, only AWS free credits for new customers (6 months, $200 limit); Balto the prompts only work if agents read them, and on floors with fast handle-time targets agents learn to ignore the panel, which turns an expensive live system into an ordinary after-the-fact scorer.
  • They diverge on capability: Amazon Lex covers Speech recognition, Balto covers Real-time prompts.
  • Prices and features above were last checked on 31 August 2026.

Balto

Where each one falls short

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

Amazon Lex

  • Pay-as-you-go model with no standard free tier, only AWS free credits for new customers (6 months, $200 limit)
  • Speech requests cost $0.004 each, text requests $0.00075 each, training costs $0.50 per minute
  • Variable costs can accumulate quickly for high-volume applications

Balto

  • The prompts only work if agents read them, and on floors with fast handle-time targets agents learn to ignore the panel, which turns an expensive live system into an ordinary after-the-fact scorer.
  • Playbooks are trigger-phrase driven and need continuous maintenance as products, scripts and objections change, so the tool quietly degrades unless someone owns it as a standing job.
  • Real-time transcription on noisy lines and strong accents misfires, producing prompts that fire on the wrong cue and train agents to distrust the panel entirely.
  • It is voice-first, so a contact centre where most volume has moved to chat and messaging gets far less from it than the per-agent price implies.
  • No pricing is published and there is no self-serve tier, so evaluating it means a sales cycle plus a technical integration into your telephony before you can judge whether agents will actually use it.

Answered from the vendors’ own pages

Amazon Lex: How much does Amazon Lex cost?

Amazon Lex charges $0.004 per speech request and $0.00075 per text request with no upfront commitments or minimum fees required.

Source
Balto: How is this different from Gong or Chorus?

Those analyse calls after they end. Balto changes the call while it is happening by prompting the agent live, which matters for compliance and much less for post-hoc coaching.

Amazon Lex: Is there a free tier for Amazon Lex?

Yes, new AWS customers receive 10,000 text requests and 5,000 speech requests per month free for the first year. Additional $200 in AWS Free Tier credits are available for new customers as of July 15, 2025, with all credits expiring within 12 months.

Source
Balto: Does it need my telephony vendor to cooperate?

Yes. It needs a live audio stream, so it integrates at the CCaaS or dialler layer with Five9, Genesys, Amazon Connect and similar. An unsupported platform is a blocker, not a config change.

Amazon Lex: What is the example monthly cost for Amazon Lex?

For 8,000 speech requests ($32) and 2,000 text requests ($1.50), the approximate monthly total is $33.50, though actual costs vary based on usage volume.

Source
Balto: What does it cost?

Balto does not publish pricing. Expect a quoted per-agent annual contract, with the rate depending on seat count and which modules you licence.

Balto: Will it work for chat teams?

Not well. The product is built around live voice, and text channels are not where its strength is.
