This is an n8n community node. It lets you use Speechify's text-to-speech API in your n8n workflows.
Speechify provides high-quality, low-latency text-to-speech generation and a
catalog of voices, via a REST API at https://api.speechify.ai.
n8n is a fair-code licensed workflow automation platform.
Installation Operations Credentials Compatibility Usage Resources Version history
Follow the installation guide
in the n8n community nodes documentation, and install @speechify/n8n-nodes-speechify.
- Generate Audio — converts input text to an audio file using a chosen
voice and model, and writes the result to a binary property on the output
item (default
data) so it can be passed straight into nodes like Write Binary File, HTTP Request (as a multipart field), or a webhook response. Model, Voice and Language are live dropdowns and they cascade: the selected model narrows the voices and languages to the set it supports (e.g. an English-only model hides non-English voices). Extra options — audio/output format, loudness and text normalization — live under Add Field.
- Get Many — lists the voices available to your Speechify account, with
type/localefilters, "Return All" / "Limit", and a "Simplify" toggle for a trimmed-downvoiceId/displayName/gender/locale/languagesshape instead of the raw API response. Handy for building your own voice-selection logic; the Generate Audio operation has its own searchable Voice picker, so you don't need this just to find an ID.
This node uses the Speechify API credential type: a single API Key
field. Generate a key from the Speechify API console and paste it in — the
node sends it as Authorization: Bearer <your key> on every request. Use the
"Test" button on the credential to confirm it before you build a workflow.
Connect the credential first. The Voice, Model and Language fields are dropdowns populated live from the Speechify API using your key. They only load once a valid credential is selected on the node — until then they stay empty. If a dropdown won't populate, re-check the credential with its "Test" button.
Built and tested against n8n-workflow as scaffolded by @n8n/node-cli
(n8n n8nNodesApiVersion: 1). No known incompatibilities.
All configuration — the API key, the text, the voice, the model, the audio format — is supplied via node parameters and the credential. This node never reads environment variables or the filesystem for configuration, per n8n's community-node verification requirements.
Every request this node sends to api.speechify.ai includes a
Speechify-Caller: n8n attribution header (see
nodes/Speechify/GenericFunctions.ts) so Speechify can attribute usage to
this integration. If you fork this node, keep that header — it's a required
piece of the integration, not incidental.
