Text To Speech

Text to Speech

Convert any text to natural-sounding speech in 32 languages 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 this text to speech with a clear, professional female voice: Artificial intelligence is reshaping how we create, communicate, and connect. What was once science fiction is now everyday reality."}],
    "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 this text to speech with a clear, professional female voice: Artificial intelligence is reshaping how we create, communicate, and connect. What was once science fiction is now everyday reality."}]
)

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": "Describe this image aloud using text-to-speech. Use a warm, conversational voice as if explaining the scene to a friend."},
              {"type": "image_url", "image_url": {"url": "https://example.com/photo.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.

Common Pitfalls

• No voice description produces a default voice. Always specify gender, style, and mood.
• All caps text may be read letter-by-letter. Use normal casing with emphasis described in the prompt.
• Numbers and abbreviations can be misread. Write out "twenty-five" instead of "25" for reliability.
• Very long texts without paragraph breaks sound monotone. Break into logical sections.
• Missing language specification for non-English text may produce incorrect pronunciation.
• Special characters and code snippets may produce unexpected audio. Describe technical content in natural language.
