Migrate from speechify to elevenlabs.
2 documentation-derived translation patterns — what carries over and what to watch for. Cited to the Feature Parity Map; the audit tells you whether the move is worth it.
Consolidate Speechify's listening/read-aloud use case into ElevenLabs Text-to-Speech. Speechify is consumption-first (paste text or open a document and listen via extension/app), while ElevenLabs is generation-first (produce audio files from text). To move the workflow, paste or upload the source text into the ElevenLabs TTS tool (or Studio for long-form), choose a Voice Library voice and model, and generate downloadable audio to listen to. For browsing-while-listening habits, treat ElevenLabs as a render step that produces an audio file rather than an in-browser reader overlay.
- Warning: ElevenLabs has no read-along browser extension or OCR document importer: it generates audio from supplied text, so Speechify's 'open any PDF/web page and press play' convenience and Scan & Listen do not carry over.
- Warning: Speechify is sold as a flat consumer subscription with effectively open listening, whereas ElevenLabs meters per-character credits, so heavy daily listening can consume credits quickly and cost more than a fixed Premium plan.
- Warning: Per-generation character caps apply on ElevenLabs (e.g. ~5,000-10,000 chars per request depending on model), so a long book or article must be chunked, unlike Speechify which streams an entire document continuously.
Move programmatic speech generation off the Speechify TTS API onto the ElevenLabs API. Swap the base endpoint and auth (Speechify bearer token to ElevenLabs xi-api-key header), then re-point text-to-speech calls; both offer official Python and JavaScript/TypeScript SDKs, so the SDK call shape is the closest analog. Map each Speechify voice to an ElevenLabs voice_id (from the Voice Library or a cloned voice) and pick an ElevenLabs model (e.g. Multilingual v2 for quality or Flash v2.5 for low latency). Translate billing expectations from Speechify's $10 / 1M characters flat rate to ElevenLabs' per-character credit consumption under a chosen plan.
- Warning: Billing models differ: Speechify is simple pay-as-you-go ($10/1M chars), while ElevenLabs meters character-based credits against tiered monthly plans, so per-character cost varies by plan and model rather than being a single flat rate.
- Warning: Output format support differs: Speechify's API emits MP3 and WAV, whereas ElevenLabs adds PCM, Opus, and ulaw/alaw — but some high-fidelity formats (44.1 kHz PCM, 192 kbps MP3) are gated to Pro/Creator tiers.
- Warning: SSML and voice-cloning semantics are not identical: Speechify exposes SSML plus 10+ named emotions, while ElevenLabs v3 controls delivery via inline audio tags and has its own Instant vs Professional voice-cloning tiers with consent verification, so prompts and clone assets must be re-authored, not copied verbatim.
