  4. Copyright: Consider voice rights and ownership

For your own voice:

  • Great for maintaining consistency
  • Useful for corrections without re-recording
  • Consider disclosure when appropriate

For others' voices:

  • Get explicit written permission
  • Document the agreement
  • Use only for agreed purposes
  • Be aware of legal implications

For public/commercial use:

  • Use stock voices or licensed voices
  • Avoid imitating real people
  • Follow platform terms of service

Technical Integration

API Quick Start (ElevenLabs Example)

import requests

API_KEY = "your_api_key"
VOICE_ID = "21m00Tcm4TlvDq8ikWAM"  # Rachel voice

url = f"https://api.elevenlabs.io/v1/text-to-speech/{VOICE_ID}"

headers = {
    "Accept": "audio/mpeg",
    "Content-Type": "application/json",
    "xi-api-key": API_KEY
}

data = {
    "text": "Hello! This is a test of the ElevenLabs API.",
    "model_id": "eleven_monolingual_v1",
    "voice_settings": {
        "stability": 0.5,
        "similarity_boost": 0.5
    }
}

response = requests.post(url, json=data, headers=headers)

with open("output.mp3", "wb") as f:
    f.write(response.content)

SSML for Better Control

Most TTS services support SSML (Speech Synthesis Markup Language):

<speak>
  Hello, welcome to our service.
  <break time="500ms"/>
  Let me tell you about our <emphasis level="strong">special offer</emphasis>.
  <prosody rate="slow">This is important information.</prosody>
</speak>

Common SSML tags:

  • <break> - Add pauses
  • <emphasis> - Stress words
  • <prosody> - Control rate, pitch, volume
  • <say-as> - Interpret content (dates, numbers)
  • <phoneme> - Specific pronunciation
