Text To Speech

Text to Speech

Convert written text into natural, human-sounding speech using each::sense — the intelligent AI agent that automatically selects the best model for your request.

Quick Start

Requires an each::labs API key. Get one at eachlabs.ai.

Using curl

curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -d '{
    "messages": [
      {
        "role": "user",
        "content": "Convert to speech with a warm female voice: Welcome to the Sunrise Meditation podcast. Today we will explore breathing techniques that help you start your morning with clarity and calm."
      }
    ],
    "stream": false
  }'

Using Python (OpenAI SDK)

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_EACHLABS_API_KEY",
    base_url="https://eachsense-agent.core.eachlabs.run/v1"
)

response = client.chat.completions.create(
    model="eachsense/beta",
    messages=[{
        "role": "user",
        "content": "Convert to speech with a warm female voice: Welcome to the Sunrise Meditation podcast. Today we will explore breathing techniques that help you start your morning with clarity and calm."
    }]
)

print(response.choices[0].message.content)

Streaming

Set "stream": true for real-time SSE responses, or "stream": false for complete result in a single response. Streaming is useful for showing progress in UIs; non-streaming is simpler for scripts and automation.

Voice Characteristics

Prompt Engineering Tips

Specify Voice Details

Be explicit about the voice you want. Include gender, tone, pace, and accent in your prompt for best results.

Convert to speech with a [gender] [accent] voice, [tone] tone, [pace] pace: [your text]

Punctuation Matters

• Use commas for natural pauses
• Use periods for full stops
• Use ellipses (...) for dramatic pauses
• Use exclamation marks for emphasis

Long-Form Content

For long text, break it into paragraphs. The AI handles multi-paragraph content but shorter segments give you more control over pacing and tone.
