Where each one falls short

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

ElevenLabs

  • Number pronunciation errors: '200000' reads as 'twenty thousand thousand' instead of '200,000'
  • Voice cloning requires professional-grade audio quality; no upfront guidance on technical requirements
  • Email-only support with 5-14 day response times for complex issues; no phone support
  • Pricing unpredictability: actual usage often exceeds advertised estimates due to regenerations needed for quality

AI21 Labs

  • The free allowance is $10 of credit lasting 7 days rather than an ongoing free tier
  • Jamba Large is $2 per million input tokens and $8 per million output, so output-heavy work costs four times as much as input
  • Volume discounts, private cloud hosting and higher rate limits require a custom plan
  • Standard rate limits are not published

ElevenLabs: How many languages does ElevenLabs support?

ElevenLabs supports voice generation in 32+ languages. Professional Voice Cloning (PVC) allows you to create a digital replica of your voice that works across these 32+ languages while maintaining emotional register and prosody.

Source
ElevenLabs: What are the requirements for voice cloning?

Professional voice cloning requires high-quality audio with RMS between -23dB to -18dB, no background noise, consistent microphone distance, and proper compression. Without meeting these technical requirements, the cloned voice sounds robotic or distorted. ElevenLabs does not disclose these requirements upfront.

Source
ElevenLabs: How is pricing calculated?

ElevenLabs uses a credit-based system where monthly character limits determine your plan. Free plan has 10,000 characters/month. Starter tier ($5/month) provides 30,000 characters. Creator ($22/month) includes 121,000 credits. Annual billing offers approximately 17% savings (2 free months equivalent).

Source
ElevenLabs: What happens if I exceed my monthly character limit?

Exceeding your monthly quota requires upgrading to a higher plan. Users report pricing unpredictability, with actual usage averaging 220-280 credits per 1,000 characters when accounting for regenerations, often exceeding advertised usage estimates.
