The model supports multiple languages and voice personalities, making it suitable for content creators, developers, and professionals who need high-quality voice synthesis.
Minimax Speech 02’s core strength lies in its ability to maintain natural speech patterns while providing granular control over vocal characteristics. Whether you're creating voiceovers for videos, developing interactive applications, or producing audio content, Speech 02 HD/Turbo delivers consistent, professional-quality results that sound authentically human.
Technical Specifications
Minimax Speech generates high-quality audio with configurable sample rates up to 44100 Hz and bitrates up to 256000 kbps. The model produces professional-grade speech suitable for broadcast, commercial applications, and interactive media across multiple languages and voice personalities.
2. Getting Started with Minimax Speech
2.1 Model Selection
When generating audio in Scenario, select Minimax Speech 02 HD/Turbo from the model dropdown in the Generate Audio section. Minimax Speech is optimized for natural speech synthesis and works best with clear, well-structured text input that includes proper punctuation and formatting.
2.2 Understanding the Interface
The Minimax Speech 02 interface provides comprehensive voice control through several key categories:
Text Field: Where you input the text to be spoken
Voice Controls: Voice ID, Speed, Volume, Pitch, and Emotion settings
Language Settings: English Normalization and Language Boost options
Audio Quality: Sample Rate, Bitrate, and Channel configuration
3. Voice Control Settings
3.1 Voice ID Selection
Choose from a diverse range of voice personalities, each with distinct characteristics and speaking styles. Options include professional voices like "Wise_Woman" and "Elegant_Man," casual personalities like "Friendly_Person" and "Casual_Guy," and specialized voices like "Young_Knight" and "Inspirational_girl." Each voice ID has unique tonal qualities, age characteristics, and speaking patterns optimized for different content types.
3.2 Speed Control
Adjust the speaking rate from slow, deliberate delivery to fast-paced narration. Lower values create more contemplative, educational pacing, while higher values work well for energetic content or when fitting speech into time constraints. The default setting provides natural conversational speed.
3.3 Volume Adjustment
Control the overall loudness of the generated speech. This setting affects the amplitude of the audio output without changing the voice characteristics. Use higher values for content that needs to cut through background noise or lower values for intimate, close-listening scenarios.
3.4 Pitch Modification
Alter the fundamental frequency of the voice to create variations in tone. Lower the pitch for deeper, more authoritative delivery, while higher values raise the pitch for lighter, more energetic speech. Subtle adjustments maintain naturalness while providing tonal variety.
3.5 Emotion Settings
Select from emotional states including neutral, happy, sad, angry, fearful, disgusted, and surprised. The "auto" setting allows the model to interpret emotional context from the text content. Each emotion affects not just tone but also pacing, emphasis, and vocal inflection patterns.
4. Language and Processing Settings
4.1 English Normalization
When enabled, this feature optimizes text processing for English content by handling abbreviations, numbers, and special characters more effectively. It ensures proper pronunciation of dates, currency, measurements, and common abbreviations in English text.
4.2 Language Boost
Enhance pronunciation accuracy for specific languages when working with multilingual content or non-English text. Options include major world languages like Chinese, Spanish, French, German, and many others. This setting helps the model better handle language-specific phonetics and pronunciation rules.
5. Audio Quality Configuration
5.1 Sample Rate Options
Choose from multiple sample rates (8000Hz to 44100Hz) based on your quality requirements. Higher sample rates like 32000Hz and 44100Hz provide better audio fidelity for professional applications, while lower rates like 16000Hz and 22050Hz create smaller files suitable for web applications or bandwidth-limited scenarios.
5.2 Bitrate Selection
Control audio compression quality with bitrate options from 32000 to 256000 kbps. Higher bitrates preserve more audio detail and dynamic range, essential for professional broadcast or high-quality content. Lower bitrates reduce file size for streaming applications or storage-constrained environments.
5.3 Channel Configuration
Select between mono and stereo output. Mono provides single-channel audio suitable for most speech applications and reduces file size. Stereo output can enhance spatial presence and is preferred for content that will be mixed with other stereo audio elements.
6. Text Input Best Practices
Write clear, properly punctuated text for optimal results. Use periods, commas, and question marks to guide natural pacing and intonation. Break long passages into shorter sentences for better flow. Include pronunciation guides for unusual names or technical terms using phonetic spelling in parentheses.
For dialogue or character voices, consider using different Voice IDs and Emotion settings to create distinct personalities. Adjust Speed and Pitch settings to further differentiate characters or match specific content requirements.
Write clear, properly punctuated text for optimal results. Use periods, commas, and question marks to guide natural pacing and intonation. Break long passages into shorter sentences for better flow. Include pronunciation guides for unusual names or technical terms using phonetic spelling in parentheses. For example:
Good
"Welcome to our presentation. Today, we'll explore three key topics. First, market analysis. Second, customer feedback. Finally, future strategies."
Avoid
"Welcome to our presentation today we'll explore three key topics first market analysis second customer feedback finally future strategies"
Pronunciation guides
"Meet Dr. Xiaoping (SHAO-ping) from the research team" or "The new AI model, called GPT (G-P-T), shows remarkable results."
Numbers and dates
Write "March fifteenth, twenty twenty-four" instead of "3/15/2024" for more natural speech.
For dialogue or character voices, consider using different Voice IDs and Emotion settings to create distinct personalities. Adjust Speed and Pitch settings to further differentiate characters or match specific content requirements. Some character examples are
Narrator: Wise_Woman voice, neutral emotion, normal speed
Excited character: Lively_Girl voice, happy emotion, increased speed
Villain: Deep_Voice_Man, angry emotion, slower speed, lower pitch
7. Creative Applications and Use Cases
Use Minimax Speech 02 for video narration, podcast production, e-learning content, and interactive applications. Create character voices for games, generate multilingual content for global audiences, or produce accessibility-focused audio versions of written content. The natural-sounding output works well for commercial applications, educational materials, and entertainment projects.
8. Asset Management and Workflow
Generated speech can be previewed directly in Scenario, downloaded in your chosen quality settings, organized with custom tags, and shared with collaborators. Use Scenario's asset management tools to build voice libraries for consistent character voices or organize content by project, language, or voice style.
9. Optimization and Troubleshooting
For best results, match voice characteristics to content type. Use professional voices for business content, casual voices for conversational material, and specialized voices for character work. Adjust emotion settings to match the intended tone, and fine-tune Speed and Pitch for optimal delivery.
If speech sounds unnatural, simplify complex sentences, check punctuation, or try different Voice IDs. For multilingual content, enable appropriate Language Boost settings and consider using English Normalization for mixed-language text with English elements.
Minimax Speech provides powerful tools for creating natural, expressive speech that enhances any audio project with professional-quality voice synthesis.
