Voice Generation

Generate human-like voice audio from text with expressive control 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": "Generate a warm, professional male voice narrating: Welcome to the future of AI. In this episode, we explore how generative media is transforming creative industries around the world."}],
    "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": "Generate a warm, professional male voice narrating: Welcome to the future of AI. In this episode, we explore how generative media is transforming creative industries around the world."}]
)

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

With Reference Image

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": [
              {"type": "text", "text": "Generate a voice narration describing what is happening in this image. Use a friendly, conversational female voice as if narrating a travel documentary."},
              {"type": "image_url", "image_url": {"url": "https://example.com/travel-scene.jpg"}}
            ]
          }
    ],
    "stream": false
  }'

Images are sent inside messages using the OpenAI multimodal content format. Maximum 4 images per request.

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.

Prompt Tips

Voice Description Formula

Generate a [voice type] [gender] voice [speaking style]:
[The text to speak]

Controlling Pace and Emotion

Add delivery instructions before the text:

"Speak slowly and calmly with pauses between sentences: ..."
"Deliver with excitement and rising energy: ..."
"Read in a serious, measured tone with gravitas: ..."

Adding Pauses and Emphasis

Use natural punctuation to control delivery:

"The results were... unexpected. (pause) Very unexpected."
"This is NOT a drill. I repeat — this is NOT a drill."

SSML-like Control

Describe the delivery style in natural language:

"Whisper the first line, then gradually increase volume
and intensity through the paragraph, ending with a powerful
declaration."

Common Pitfalls

• No voice description produces a default neutral voice. Always describe the voice character.
• Walls of text without punctuation produce rushed, monotone output. Use natural punctuation.
• Conflicting emotions (e.g., "happy and sad") confuse the delivery. Pick one dominant emotion.
• Missing language specification for non-English text may produce incorrect pronunciation.
• Very long texts should be broken into paragraphs for better pacing and natural breathing.
