ElevenLabs Japanese Text to Speech Serverless API Workflow

Overview

The ElevenLabs Japanese Text to Speech API Workflow converts any Japanese text into high-quality, natural-sounding audio using ElevenLabs' Turbo v2.5 model — all via a simple serverless API call. Whether you're building a language learning app, a podcast automation pipeline, or a customer support voice system, this workflow gives you production-ready Japanese TTS with zero infrastructure overhead.

Powered by Segmind's Pixelflow, you send a single API request with your Japanese text and instantly receive an .mp3 audio file in return. No model hosting, no GPU management — just a clean REST API.

How It Works

The workflow has three nodes connected in sequence:

1. •Text Input Node — Accepts the Japanese text string (parameter: text) that you want converted to speech.
2. •ElevenLabs Turbo v2.5 Node — Passes the text through ElevenLabs' multilingual TTS engine with language_code locked to ja (Japanese) and apply_language_text_normalization enabled, ensuring correct pronunciation of Japanese characters, numbers, and symbols.
3. •Audio Output Node — Returns the generated audio as an .mp3 file (parameter: audio).

Customization Guide

• •Voice: Change the voice parameter (default: Rachel) to any ElevenLabs voice. You can also supply a custom voice_id.
• •Model: Currently set to eleven_turbo_v2_5 for Japanese support. Switch to eleven_multilingual_v2 for higher quality at the cost of slightly more latency.
• •Stability / Similarity Boost / Speed / Style: Fine-tune expressive parameters to match your target use case.
