Speech generation AI is used in the production of videos, games, and business presentations.
However, many people may not use voice-generated AI because they feel that it is still unnatural and uncomfortable.
In this article, we will explain the evolutionary points and actual usage ofElevenLabs v3 (alpha), which has been talked about for its natural voice generation, in an easy-to-understand manner.
Please see the end of this page so you can determine if your business can incorporate voice-generated AI.
What is ElevenLabs?
ElevenLabs is a voice generation AI that utilizes deep learning.
Our text-to-speech software, which utilizes AI technology, has earned a reputation for its ability to generate natural speech and rich customizability.
Because it can generate high-quality voice data simply by entering text, it is used in a wide range of situations, including the following
- Business Presentations
- video conference
- Accent practice at a speaking school
- Content production, including video and radio distribution
- English Listening Materials
In the years since its release, ElevenLabs has become a leading AI voice tool.
This is largely due to the fact that the market’s needs coincided with the provision of realistic voice generation.
ぼーElevenLabs’ technological capabilities will further evolve the voice to be more expressive and lead the AI voice tool world.
June 2025 “ElevenLabs v3 (alpha)” is released
In June 2025, a new, more advanced version , ElevenLabs v3 (alpha), was released as a research preview.
ElevenLabs v3 (alpha) was developed in response to users’ requests for higher “expressive power.
Previous versions have also been used in a variety of professional settings.
However, there were still issues to be addressed in terms of the realism of natural entry into conversations, believable exchanges, and the ability to convey emotions in an exaggerated manner.
ぼーElevenLabs therefore rebuilt v3 (alpha) from scratch to achieve richer expressiveness.
Evolutionary points of ElevenLabs v3
In ElevenLabs v3, the realism of emotional expressions and nonverbal nuances has been greatly improved, and many more useful features have also evolved.
Here, we will explain in an easy-to-understand manner how v3 has evolved in comparison with the previous versions.
Realistic reproduction of emotional and nonverbal expressions
In ElevenLabs v3 , emotional expression, which has been a challenge in the past, has evolved significantly.
ElevenLabs v3 allows AI to automatically control intonation and inflection, accurately reading the emotion and intent in the text and voicing it with the appropriate tone and expression.
ぼーIf you actually let them read the text out loud, you will be amazed at their natural intonation and smooth speech.
The slow speed and subtle pauses are also very human-like, and the realism is such that you would never feel that it is an AI.
Dialogue (conversation) mode implementation
Another major evolution of ElevenLabs v3 is the implementation of “Dialogue Mode,” which generates natural conversations with multiple speakers.
In dialog mode, the AI automatically generates a conversation that includes the following elements
- Sharing of context and emotions among speakers
- Natural pace of conversation
- wedging oneself in
- Emotional transitions
Conventional speech generation AI requires that each speaker’s voice be generated separately and then combined by the user himself using audio editing software.
In dialog mode, the AI handles everything from speech generation to speech merging for each speaker.
ぼーThis greatly improves the efficiency of production work involving multiple voices, such as audio dramas, podcasts, and conversations between characters in games.
Fine control by audio tags
In ElevenLabs v3 (alpha), “audio tags” can now be used to add emotion and non-verbal expressions to speech.
An audio tag is a text tag that can be inserted within a prompt to direct a specific emotion or expression to the generated audio.
For example, the following tags are available
- Whispers: [whispers].
- Sighs: [sighs].
- Laughs: [laughs]
- Excited: [EXCITED].
These tags make it easier to express emotion and nonverbal expressions rather than simply reading text.
However, while emotions can be easily added, unintentional use of tags or unnatural combinations can make the voice sound floaty and uncomfortable to the viewer.
Therefore, users are required to have prompt design skills (i.e., prompt engineering skills), similar to “acting guidance for voice actors.
ぼーCareful design of tag positioning and timing of emotional switching is important to convey accurate intent.
Support for more than 70 languages
The number of languages supported by ElevenLabs v3 (alpha) has increased significantly from 29 to over 70.
Generation of expressive AI speech in the following major languages is possible
- English (language)
- Japanese (language)
- Chinese (language)
- Portuguese
- German (language)
- Hindi, etc.
Until now, AI voice technology has been developed primarily in English.
Improvement of text comprehension
In ElevenLabs v3 (alpha), AI’s ability to understand text has been greatly improved text comprehension.
This enables the system to read the meaning and context of a sentence and automatically adjust appropriate emphasis and intonation to produce a more natural sounding voice.
It is now possible for AI to understand the relationship between words and the structure of sentences, and to emphasize important parts and change the way emotions are put into words.
ぼーThis allows for human-like narration and reading without the need for detailed prompting by the user.
