The short version

  • Only Amazon Lex has a free tier, so it costs nothing to try first.
  • Each has a real cost: Alvaria the October 2025 restructuring wrote off more than 75% of roughly $950 million of debt and handed control to a lender group led by Nut Tree Capital, so the owner is now a credit fund optimising for debt recovery rather than a growth investor, which is a real signal about future research spending.; Amazon Lex pay-as-you-go model with no standard free tier, only AWS free credits for new customers (6 months, $200 limit)
  • They diverge on capability: Alvaria covers Compliant outbound dialling, Amazon Lex covers Speech recognition.
  • 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.

Alvaria

  • The October 2025 restructuring wrote off more than 75% of roughly $950 million of debt and handed control to a lender group led by Nut Tree Capital, so the owner is now a credit fund optimising for debt recovery rather than a growth investor, which is a real signal about future research spending.
  • The September 2024 spin-out of the workforce management suite to the revived Aspect brand means a buyer who wanted an integrated CX plus WFM stack now signs two contracts with two companies, and first-party integration is no longer guaranteed by a single roadmap.
  • Digital channels are underbuilt: reviewers report CXP has no support for WhatsApp, RCS or Viber, and no ability to bring your own carrier for email and SMS, which blocks messaging-first and many international deployments.
  • Legacy on-premise upgrades are described by reviewers as long and painful, with a large footprint and hard-to-learn interdependencies, so migration cost is a substantial hidden line item on any modernisation.
  • Alvaria is slower than peers to certify new Nuance speech recognition and text-to-speech releases, so speech quality in your IVR runs behind whatever the underlying engine has shipped.
  • There is no published pricing, no trial and a mixed on-premise and cloud licensing model, making like-for-like comparison against Genesys, Five9 or NICE genuinely difficult and lengthening the evaluation.

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

Answered from the vendors’ own pages

Alvaria: Was Alvaria renamed to Aspect?

No. It split. Aspect is the spun-out workforce management business at aspect.com. Alvaria kept outbound and contact centre infrastructure. Confusing the two points procurement at the wrong vendor.

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

Alvaria: Who owns Alvaria now?

Since October 2025, a lender group led by Nut Tree Capital, following an out-of-court debt restructuring. Abry Partners no longer controls the 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.

Alvaria: Can I still buy on-premise?

Yes. Cloud, on-premise and hybrid deployments are all offered, which is one of the few remaining reasons to choose Alvaria over a pure CCaaS vendor.

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.
