Use when adding voice input (speech-to-text) or voice output (text-to-speech) to AI agents in a Pikku app. Covers voiceInput/voiceOutput middleware hooks and STT/TTS service interfaces. TRIGGER when: code uses voiceInput, voiceOutput, STTService, TTSService, or user asks about voice, speech-to-text, text-to-speech, or @pikku/ai-voice. DO NOT TRIGGER when: user asks about AI agent wiring (use pikku-ai-agent) or Vercel AI SDK (use pikku-ai-vercel).

@pikku/ai-voice provides speech-to-text and text-to-speech middleware hooks for Pikku AI agents.
yarn add @pikku/ai-voice
interface STTService {
transcribe(audio: Uint8Array, options?: { language?: string; format?: string }): Promise<string>
}
interface TTSService {
synthesize(text: string, options?: { voice?: string; format?: string }): Promise<Uint8Array>
synthesizeStream?(text: string, options?: { voice?: string; format?: string }): AsyncIterable<Uint8Array>
}
import { voiceInput, voiceOutput } from '@pikku/ai-voice'
voiceInput(config?: { language?: string }): PikkuAIMiddlewareHooks
voiceOutput(config?: { format?: string; voice?: string }): PikkuAIMiddlewareHooks
These return middleware hooks that can be attached to AI agent wirings to automatically transcribe audio input and synthesize audio output.
import { voiceInput, voiceOutput } from '@pikku/ai-voice'
import { wireAIAgent } from '@pikku/core/ai-agent'
wireAIAgent({
name: 'voice-assistant',
model: 'openai:gpt-4o',
systemPrompt: 'You are a voice assistant.',
middlewareHooks: [
voiceInput({ language: 'en' }),
voiceOutput({ voice: 'alloy', format: 'mp3' }),
],
func: myAgentFunc,
})
Implement the STTService and TTSService interfaces with your provider (OpenAI Whisper, ElevenLabs, etc.) and register them as singleton services.
documentation
Standard cleanup to run right after a Pikku template is cloned or scaffolded into a new project. TRIGGER when: a Pikku template was just cloned/scaffolded (via `pikku create`, `git clone <template>`, or the user says "I cloned the kanban template / starter / template"), or the working tree still looks like an untouched template (template README, placeholder `@project/*` name in package.json). DO NOT TRIGGER when: working in an established project mid-feature, or editing the template repo itself.
development
Make a Pikku frontend work in both English (LTR) and Arabic / right-to-left languages. Direction is derived from the active locale, applied once at the document root, and the layout mirrors itself — but only if styling is written flow-relative (margin-inline-start, text-align: start, Mantine ms/me) instead of left/right. TRIGGER when: adding Arabic (or Hebrew/Farsi/Urdu), asked to "support RTL / right-to-left / bidi / mirror the layout", or writing layout styles in an app that may run RTL. Builds on pikku-i18n (an RTL language is just another locale file). DO NOT TRIGGER for backend functions or for LTR-only copy changes.
development
Wire i18n into a Pikku frontend (Vite SPA, Vite SSR, or Next.js app-router) with react-i18next + i18next. English by default, every user-facing string goes through a `t()` token, and additional languages are served under `/de` `/es` URL prefixes. TRIGGER when: scaffolding or editing a frontend and writing user-facing text, adding a second language, or asked to "make this translatable / use tokens / add i18n". DO NOT TRIGGER for backend functions, error messages thrown from functions, or log output.
development
Use when translating an n8n Code node body into a real Pikku function body. Triggered when the user opens or points at a stub generated by @pikku/n8n-import (look for `STUB — generated from n8n Code node` in the file's JSDoc), or when the user says 'translate this n8n code', 'port this n8n code node', 'finish the codeStub__... function', etc. The stub file is a `pikkuSessionlessFunc` with a Zod input/output, a JSDoc preserving the original n8n JavaScript verbatim, and a `throw new Error('… — implement me')` body.
