How they stack up

Choose Reader, Studio, or the API

Speechify's products serve different jobs. Reader is for listening to written material. Studio is for producing content, and SpeechifyAI is for generating speech inside software.

  • For a video voiceover, compare Speechify Studio with the ElevenLabs creation workflow.
  • For a speaking application, compare SpeechifyAI with the ElevenLabs API.

Speechify's Studio pricing FAQ confirms that Reader and Studio are separate subscriptions. A Reader plan does not establish your Studio or API allowance.

Compare the selected model and language

SpeechifyAI recommends Simba 3.2 for English and Simba 3.0 for multilingual integrations. ElevenLabs also has different models for expressive narration and latency-sensitive speech. A single brand-wide language count hides those choices.

  • Test the target language with the exact voice and model you will use.
  • Include names, pronunciation-sensitive phrases, and any requested changes in delivery.

Check the SpeechifyAI model guide and ElevenLabs model guide before building around a particular voice.

Compare the allowance you will consume

SpeechifyAI meters API speech by characters. Speechify Studio uses its own credits for content production. ElevenAPI lists character rates, while ElevenLabs creative plans have separate allowances.

  • Estimate generated text and revisions for an API workload.
  • Include Studio production features and exports when budgeting finished voiceovers.
  • Check whether the plan includes cloning and the capacity your application needs.

Use SpeechifyAI pricing, Speechify Studio pricing, and ElevenLabs pricing. A consumer listening subscription is not a quote for generating speech through an API.

Frequently asked questions

Is Speechify Reader the same product as Speechify Studio?

No. Reader reads documents, articles, and other text aloud. Studio is for creating voiceovers and dubbed content, and it has a separate subscription. SpeechifyAI is the developer platform. Choose the relevant product before comparing its price with an ElevenLabs speech-generation plan.

Should I compare ElevenLabs with Speechify Studio or the API?

Compare Studio if you are creating voiceovers in an editor. Compare SpeechifyAI if your application needs to generate or stream speech. Test a complete production workflow for content creation, or an actual speech request and playback flow for software integration. For another editor-based voiceover option, see ElevenLabs vs Typecast.

Does Speechify have a real-time speech API?

Yes. SpeechifyAI has a streaming speech endpoint and streaming-native Simba models. ElevenLabs also supports streaming speech. Select the model and voice before testing, and measure when audio is playable in your application. A provider's first-byte measurement can differ from the delay your listener experiences.

Which SpeechifyAI model should I compare with ElevenLabs?

SpeechifyAI recommends Simba 3.2 for English integrations and Simba 3.0 for supported multilingual speech in English, German, Spanish, French, Italian, and Brazilian Portuguese. Spanish has Spain and Mexico locales. Pick the ElevenLabs model for the same language and workload. Check SpeechifyAI's model guide for voice compatibility rather than assuming every voice supports every model.

Can I clone my voice with ElevenLabs and Speechify?

Both support voice cloning. ElevenLabs has instant and professional workflows with different plan requirements. SpeechifyAI offers cloning on paid plans and requires a voice sample plus a recorded consent challenge. Its cloning guide describes the process. Speechify Studio has separate plan entitlements.

How do ElevenLabs and Speechify API costs compare?

SpeechifyAI Starter is $10/month with 1.9 million characters; additional usage costs $10 per million characters through top-ups. ElevenAPI lists Flash/Turbo at $0.04 and Multilingual v2 at $0.08 per 1,000 characters, excluding taxes. Compare ElevenAPI pricing with SpeechifyAI pricing for your model and monthly volume. Speechify Reader subscriptions and Studio credits are separate.

Can I keep my voice and emotion settings when switching providers?

Voice IDs and control formats are provider-specific. SpeechifyAI uses SSML for supported delivery controls, while ElevenLabs settings depend on the model. Recreate permitted custom voices from the original recordings, translate the controls, and test the resulting speech. The same instruction may produce different delivery.

When should I consider Cartesia as another option?

Include Cartesia when comparing speech APIs for your application. Test Sonic with the same scripts and audio requirements as ElevenLabs and SpeechifyAI, then compare cloning access and production costs. Its WebSocket API supports speech contexts and cancellation. Evaluate document-reading or video-editing features separately.
