Emotional speech synthesis
Practice scenario
Practice a realistic conversation with our AI employee. Improve your conversation skills in a safe environment.
More than text-to-speech
Emotional nuances make the difference between a mere exercise and realistic training—in sales, service, leadership, and interviewing.
Dynamic speaking pace
A nervous applicant speaks faster. A skeptical buyer takes longer pauses to think. An angry customer becomes increasingly agitated. Our AI voices adjust their pace to match the emotional state – across all training types.
Tempo varies depending on emotional state.
Breaks during skepticism, reflection, uncertainty.
Acceleration in excitement, anger, enthusiasm
Consistent adaptation to the conversation flow.
Emotional tone coloring
When an objection is overcome, you can hear it. When the customer calms down, you can feel it. The voice conveys skepticism, frustration, interest, or openness—not through exaggerated theatrics, but through subtle nuances, just like in real conversations.
Audible skepticism in price discussions
Relaxation through successful objection handling
Trouble with customer service escalations
Interest and openness through effective needs analysis.
Volume and emphasis
A confident decision-maker speaks louder and emphasizes differently than an insecure employee. An escalating customer becomes louder, while a conciliatory one becomes quieter. Our AI utilizes volume and emphasis as means of expression for realistic conversation dynamics.
Volume adapts to the situation and emotion.
Emphasis signals importance and objections.
Quieter when steering or yielding.
Become louder in moments of escalation or excitement.
Training in Emotional Awareness
The ability to recognize emotional signals in the voice is crucial—whether in sales conversations, customer interactions, or employee discussions. Identify buying signals, detect frustration early, and respond to openings. You will train this perception here.

How does emotional language variation aid in sales training?
In sales, vocal signals are often the key: Do you hear genuine interest or polite rejection? Is the objection serious or a buying signal? Our emotional speech synthesis trains you to recognize these nuances. You’ll learn to discern when the buyer is contemplating rather than rejecting, when skepticism turns into interest, or when a price objection is merely a pretext. This makes you more attentive in real sales conversations.
What emotions can the AI voice convey?
The speech synthesis covers a wide range of emotions: skepticism and rejection, interest and openness, anger and frustration, as well as relief, enthusiasm, and agreement. Crucially, these emotions are not static; they evolve throughout the conversation. A dialogue can start with a skeptical tone and, with effective communication, end in an interested tone—or vice versa.
Does the training also help for phone and video calls?
This training is especially valuable for phone and video calls. In in-person meetings, you also have body language and facial expressions. On the phone or with the camera off, your voice is your only channel. Whether in a sales call, customer service call, or remote employee conversation, the emotional perception you develop here directly translates to these situations.
Can I adjust the intensity of the emotional reactions?
In the scenario generator, you can determine how emotionally a character reacts. A slightly skeptical buyer displays a different intensity than a highly angry customer. We recommend moderate scenarios for beginners. Advanced users can take on characters with strong emotional fluctuations, such as the escalating customer or the highly frustrated employee.
How realistic do the emotional variations sound?
Our speech synthesis utilizes advanced text-to-speech technology that goes far beyond monotonous computer-generated voices. The emotional variations are subtle and natural—we avoid theatrical exaggerations. Users report that after just a few minutes, they forget they are speaking with an AI because the emotional cues feel authentic. The voice dynamically responds to the flow of conversation.
