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); Playvox niCE acquired Playvox in 2023 and also sells CXone above it, so at renewal you are negotiating with a vendor that has a commercial incentive to move you to the more expensive tier rather than invest in the one you bought.
  • They diverge on capability: Amazon Lex covers Speech recognition, Playvox covers Quality management.
  • Prices and features above were last checked on 31 August 2026.

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

Playvox

  • NiCE acquired Playvox in 2023 and also sells CXone above it, so at renewal you are negotiating with a vendor that has a commercial incentive to move you to the more expensive tier rather than invest in the one you bought.
  • Playvox WFM carries a minimum agent commitment reported around 35 seats, so a team of 20 either pays for agents it does not have or cannot buy the module at all.
  • The suite is modular and priced modularly, so the quality, performance, coaching, WFM and analytics pieces each carry a line item and the advertised mid-market saving disappears once you licence three or four of them.
  • Forecasting was built around digital and omnichannel volume, and teams with complex voice requirements such as skills-based routing with heavy shrinkage rules routinely find the scheduling engine less precise than dedicated voice WFM tools.
  • Because it sits on top of another vendor helpdesk rather than owning the interaction data, scoring depends on connector fidelity, and when a source platform changes its API or its recording retention the scorecards go stale before anyone notices.

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
Playvox: Is Playvox still sold as its own product?

Yes, as Playvox by NiCE. It is a distinct SKU beneath NiCE CXone, not a discontinued brand, but it is sold by NiCE sales rather than an independent company.

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
Playvox: Do I need NiCE CXone to use it?

No. Playvox connects to Zendesk, Salesforce, Freshdesk, Genesys and others. Running it against a competitor platform is supported, though it is not where the vendor makes the most money.

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
Playvox: What does it actually cost?

Nothing is published. Full-suite list pricing reported by buyers sits around 70 to 120 US dollars per agent per month, with WFM alone around 30 to 60, before volume discounting.

Playvox: Can a 15-agent team buy it?

Not realistically for WFM, which carries a minimum seat commitment. Quality management alone is more accessible but still sold on an annual quoted contract.
