Voice features used to mean “glue three vendors together”: one TTS API, one STT API, and something awkward for duplex calls. For a lot of product spikes and content checks, that is overkill. You just need a free AI voice surface in the browser.
That is the niche **[NorSpeak](https://norspeak.com/?utm_source=devto&utm_medium=blog&utm_campaign=post-launch)** aims at—a free aivoice workbench with:
There is a dedicated free-AI-voice page at [norspeak.com/free-aivoice](https://norspeak.com/free-aivoice?utm_source=devto&utm_medium=blog&utm_campaign=post-launch).
Paste the line you would otherwise record yourself. Export MP3, drop it into a prototype, Notion doc, or QA checklist. Six voices is enough to A/B “does this tone feel on-brand?” without spinning up a full ElevenLabs-style project.
Open the studio when you need to feel latency and caption quality together—not as separate demos. Captions make it easier to share a call with teammates who cannot listen with sound on.
For meeting scraps or voice memos, upload and read. You are not replacing your production ASR pipeline on day one; you are validating whether a transcript is “good enough” before you write glue code. NorSpeak is for the opposite case: ship a tryable voice loop today, then graduate to an API key when fair-use is no longer enough.
Treat the site as the product UI and the paid key as the scale path. Do not invent endpoints you have not read in their docs—start from the live UI at norspeak.com, confirm the behavior, then decide what belongs in your own backend.

If your next ticket is “can we add voice without a three-week vendor bake-off?”, try NorSpeak in the browser first: TTS MP3, STT upload, and live captioned calls under fair-use—then buy quota only when the spike becomes a feature.
