Voice Settings Guide

This comprehensive guide provides detailed instructions for configuring VozCraft’s voice settings to achieve optimal results for any use case. Whether you’re creating content for business, education, or entertainment, this guide will help you select the perfect voice configuration.

​
Understanding Voice Settings

VozCraft’s audio quality is determined by four interconnected settings:

Language/Accent

Primary FactorDetermines:
  • Base pronunciation rules
  • Available system voices
  • Regional accent characteristics
  • Language-specific prosody

Voice Type

Pitch & GenderControls:
  • Base pitch (0.75 or 1.30)
  • Voice gender preference
  • Rate adjustment (±0.05)
  • Overall voice character

Speed

Temporal ControlAffects:
  • Speaking rate (0.50x to 1.60x)
  • Content duration
  • Clarity vs. efficiency
  • Listener comprehension

Mood

Emotional ToneModifies:
  • Pitch variation (0.70 to 1.35)
  • Rate multiplier (0.78x to 1.30x)
  • Volume (88% to 100%)
  • Emotional character

​
Step-by-Step Configuration

​
Step 1: Choose Your Language

Language selection is the most important decision and should be made first.
1

Identify Your Audience

Questions to ask:
  • What language do they speak?
  • Are they native speakers?
  • Which regional accent will they prefer?
  • Are there multiple target regions?
Examples:
  • US company: English (US)
  • Latin American content: Español (México)
  • European French audience: Français (France)
  • International English: English (US) for broadest understanding
2

Test Regional Variants

If your language has multiple regional options, test them:Example: Spanish
  1. Generate with Español (México)
  2. Generate with Español (España)
  3. Listen for:
    • Pronunciation differences
    • Accent preferences
    • Listener feedback
Common Differences:
  • Spain: “th” sound for C/Z (“gracias” = “grathias”)
  • Mexico: No “th” sound (“gracias” = “grasias”)
  • Argentina: “sh” sound for LL/Y (“calle” = “cashe”)
3

Check Voice Availability

Some languages have better voice support on certain platforms:Best Support (most platforms):
  • English (US, UK)
  • Spanish (Mexico, Spain)
  • French
  • German
  • Portuguese (Brazil)
Good Support (most modern systems):
  • Italian, Japanese, Chinese
  • English (AU, IN)
  • Spanish (other variants)
Variable Support (system-dependent):
  • Arabic, Hindi, Turkish, Russian
Action: If voice quality is poor, try a related language or different browser.
4

Make Your Selection

Click the 🌍 Voice / Accent / Region dropdown and select your chosen language.The dropdown shows:
  • Flag emoji
  • Language name (in interface language)
  • Organized by language family
Pro Tip: For international audiences with varying English proficiency, English (US) with Slow speed provides the best comprehension.

​
Step 2: Select Voice Type

Voice Type controls pitch and attempts to match appropriate system voices.
Technical Specs:
  • Pitch: 0.75 (25% lower)
  • Rate adjustment: -0.05

Gender Matching: VozCraft attempts to select system voices matching the voice type, but availability depends on your operating system. Not all systems provide both male and female voices for every language.

​
Step 3: Set the Speed

Speed should be chosen based on audience and content complexity.

Duration Impact: 2x longer than normal
  • 1000 characters: ~140 seconds vs. 70 at normal
Caution: May sound unnatural for native speakers familiar with the content.
Speed Selection Flowchart: 
Is content for language learners? 
  → Yes: Very Slow (0.50x)
  → No: Continue

Is audience non-native speakers?
  → Yes: Slow (0.75x)
  → No: Continue

Is content complex or technical?
  → Yes: Slow (0.75x)
  → No: Continue

Is time efficiency critical?
  → Yes: Fast (1.25x) or Very Fast (1.60x)
  → No: Normal (1.00x)

Mistake 3: Wrong Speed for AudienceProblem: Fast speed for elderly audience or language learnersResult: Poor comprehension, frustrated listenersSolution: Always consider audience capabilities, err on slower side
Mistake 4: Not Testing Before ProductionProblem: Generating all content before listening to sampleResult: Discover issues after time investmentSolution: Always generate and review test audio first
