Best voice and media AI
for vibe-coded apps
Updated 2026-09-18. ElevenLabs is the pick for most projects. Here is how the options compare, and how to run whichever you choose through a single Squiid key.
Short answer
- Our pick: ElevenLabs. The best sounding text to speech with a simple API, streaming output for low latency, and voice cloning when you need a consistent brand voice.
- Runner-up: Deepgram. Fast, accurate speech to text with streaming, diarisation and word timings, which is the other half of any voice feature.
- Pick something else when: AssemblyAI when you want transcription plus summarisation and topic detection in one call, Replicate or fal.ai when you want to run open image, video and audio models without managing GPUs, Stability for image generation, Runway or Luma for video generation, and Hume when emotional tone in the response matters.
Voice and media features split cleanly: text to speech, speech to text, and generating images or video. ElevenLabs is the pick for speech output, Deepgram for speech input, and Replicate or fal.ai when you want a model that does not have its own API. Latency, not quality, is usually what makes or breaks the feature.
How to choose a voice and media AI for an AI-coded app
Streaming or batch?
A voice assistant that waits for a full audio file before speaking feels broken. Check for streaming input and output, and measure time to first byte rather than total generation time. For conversational features that number is the product.
Per minute, per character, or per second of GPU?
Speech is billed per character or per minute, and model hosting is billed per second of compute. These are very different curves. A feature that looks cheap in a demo can be expensive at a thousand users, so model the cost against real session length.
Do you own the voice or likeness you are cloning?
Voice cloning and face generation carry consent and rights obligations, and provider terms are specific about them. Get written permission for any real person, and do not let an agent add a cloned voice without you knowing about it.
Hosted model or hosted API?
Replicate and fal.ai run open models for you, which gives you choice and version pinning at the cost of cold starts. A first party API like ElevenLabs gives you better latency and less control. For a product, prefer the first party API and use model hosts for the things nobody offers directly.
Output storage
Generated audio, images and video have to live somewhere. Plan the storage and CDN from the start rather than base64 encoding files into a database. See the storage guide.

Why run your voice and media AI through Squiid
One login instead of one per vendor. Squiid carries 9 voice and media AI options here and every other layer of the stack beside it. You create one account, click the service you want, and Squiid provisions it upstream. No separate signup, no separate password, no second dashboard.
One bill, at the provider's price. Usage is paid from prepaid Squiid credits at par: $1 of credit is $1 at the provider, with no markup on what the provider charges. The free plan is $0/month with a 15% fee on credit top-ups and a $50 minimum top-up. Solo is $19.97/month and its top-up fee starts at 8%, falling to 6.5%, 5% and 3.5% as trailing 30-day API spend passes $100, $500 and $2,000. Team is $29.97 per seat per month for seats 1-5, $24.97 for seats 6-20 and $19.97 above that, with the same ladder one point lower. Custom pricing is 3% or less against a commitment. Services that are sold as a monthly subscription, such as ElevenLabs's paid plan, pass through on your Squiid invoice at the provider's own price with no fee on top.
Squiid holds the upstream key. The provider credential lives in Squiid, not in your repo, not in a chat window and not in a screenshot. Your project gets one variable, SQUIID_API_KEY, and that is the only secret an agent ever needs to see. Rotating it is one click and does not touch the provider.
It works with every coding agent. Point the SDK base URL at https://api.squiid.io/v1/<service>/ and send Authorization: Bearer $SQUIID_API_KEY. Claude Code, Cursor, Codex, Gemini CLI, Copilot, Windsurf, Cline, Devin, Replit, v0 and Lovable all read environment variables the normal way. See the gateway convention.
Running out pauses, it never deletes. Squiid warns you at 75%, 90% and 100% of your balance. At zero, calls pause instead of overdrawing, and your data stays where it is. Auto top-up is optional and takes a hard monthly cap. See spend controls.
Set it up in 3 steps
Add ElevenLabs in the dashboard
Create a Squiid account, open the catalogue, and click add on ElevenLabs. Squiid creates the upstream account or project for you and holds the credential.
Put one variable in .env
Copy your Squiid key and add SQUIID_API_KEY=sq_live_… to your project's .env. Delete any provider keys you were carrying. Nothing else changes.
Point your agent at the gateway
Tell your agent that calls go to https://api.squiid.io/v1/elevenlabs/ with Authorization: Bearer $SQUIID_API_KEY. Most SDKs take a base URL option, so it is a one-line change.
In practice that is one line in your project:
SQUIID_API_KEY=sq_live_xxxxxxxxxxxxxxxxxxxxThen every call your app or your agent makes goes to the gateway with that one key:
curl https://api.squiid.io/v1/elevenlabs/... \
-H "Authorization: Bearer $SQUIID_API_KEY"Questions people ask
What is the best text to speech API for an app?
ElevenLabs for quality and streaming latency, which is what makes a voice feature feel live. Add it through Squiid and your project carries only SQUIID_API_KEY, with usage drawn from the same prepaid credits as your model and database calls.
ElevenLabs or Deepgram?
They are opposite directions. ElevenLabs turns text into speech. Deepgram turns speech into text. A full voice feature usually needs both, plus an LLM in between, and all three run through one Squiid key and one invoice.
How do I generate images in a vibe-coded app?
Use Replicate or fal.ai to run an open image model, or a first party image API if you want fewer moving parts. Pin the model version, store the output in object storage rather than in your database, and cap spending with credits.
Why is my voice assistant slow?
Almost always because a step waits for the previous one to complete. Stream the transcription, stream the model response, and stream the speech synthesis, overlapping them. Total latency is the sum of time to first byte at each hop, not of the full generations.
How is media AI billed on Squiid?
At provider list price from prepaid credits, with no markup. Squiid takes its fee when you buy credits. GPU-second and per character pricing both pass through unchanged, and calls pause at a zero balance rather than overdrawing.
One key for your voice and media AI.
