Is there a TTS API with child voices?

Yes — KidsStoryteller.ai's TTS API offers 11 real child voices across 11 languages. It's the only major TTS API that does: ElevenLabs prohibits child-like voices entirely, and Google Cloud TTS and Amazon Polly offer almost none.

Why doesn't ElevenLabs offer child voices?

ElevenLabs' safety policy prohibits children's voices and adult voices designed to sound like children anywhere on its platform. That's a reasonable policy for a general-purpose voice tool, but it leaves developers of legitimate kids' content — story apps, educational tools, children's games — with no option there.

How much does the KidsStoryteller TTS API cost?

1 credit per 1,000 characters, minimum 1 credit per request. Credit packs run $10/100, $25/300, $55/750 — so roughly $0.073–0.10 per 1,000 characters, with no monthly subscription. ElevenLabs' API runs about $0.165–0.30 per 1,000 characters and requires a plan.

The Only TTS API With Real Child Voices (2026) — at Half ElevenLabs' Price

Q: Is the API safe to use for children's apps?

Every request is screened by an AI moderation layer before synthesis — text that isn't appropriate for a kids platform is rejected and never charged. These are children's voices, so screening is non-negotiable.

The gap nobody talks about: child voices in TTS APIs

Text-to-speech APIs are everywhere in 2026 — but try to find one with a real child voice and you hit a wall:

ElevenLabs — explicitly prohibits children's voices and child-like voices on its platform. Policy, not a roadmap gap.
Google Cloud TTS — its premium Chirp 3 HD tier ships zero child voices across 50+ locales.
Amazon Polly — one neural child voice (Kevin, US English only).

If you're building a bedtime-story app, a reading tutor, an educational game, or a kids' YouTube automation pipeline, that's a real problem: children engage far more with voices that sound like them.

The exception: a TTS API built for kids' content

The KidsStoryteller.ai TTS API is purpose-built for children's content, with 11 child voices across 11 languages — English (US and British), Spanish, French, German, Portuguese (Brazil), Chinese, Italian, Japanese, Turkish, and Korean. Eight of those are genuine native child-trained neural voices, not pitch-shifted adults.

It's one REST call:

curl https://kidsstoryteller.ai/api/v1/tts \
  -H "Authorization: Bearer ksk_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"text": "Once upon a time…", "voice": "kid-girl"}' \
  --output story.mp3

Up to 20,000 characters per request (about 20 minutes of audio — long texts are synthesized seamlessly), three speed settings, MP3 out.

Pricing: half of ElevenLabs, no subscription

Billing is simple: 1 credit per 1,000 characters (minimum 1 per request), drawn from the same credit packs that power the rest of KidsStoryteller — $10 for 100, $25 for 300, $55 for 750. No plan to manage, no seats, no minimums. You're never charged for a failed request.

Built-in safety — because these are children's voices

Every API request is screened by an AI moderation layer before synthesis. Text that isn't appropriate for a kids platform is rejected (HTTP 400, no charge) — and if the moderation service itself is ever unavailable, the API refuses rather than synthesizing unscreened text in a child's voice. For developers shipping to app stores with kids' categories, that screening is a feature, not a restriction.
