How to Improve Realism of Text-to-Speech Voices

Not all text-to-speech engines are equal.

If you find that the text-to-speech (TTS) voices in ReachOut.AI sound robotic or unnatural, don't worry! We understand the importance of having realistic and natural-sounding voices for a better user experience. Here are some tips to enhance the realism of the voices:

By default, ReachOut.AI uses neural voices from Amazon, Google, Azure, and IBM. These TTS engines employ advanced algorithms and natural-sounding voices to produce more realistic speech.

ReachOut.AI also allows you to to import more voices from your external providers like ElevenLabs,, Fliki, and (and soon with and Lovo) for even more flexibility and realistic sounding outcomes! Simply go to Integrations and follow the instructions.

Basic tips:

Use the right voice for your content
Adjust the speech rate and use a soundtrack
Use punctuation (!) and commas (,)
Use <break> tags
Getting the correct pronunciation by adjusting the words accordingly.
Use SSML markups such as <emphasis> , <say-as> and <prosody> (see Amazon SSML Docs and/or Google SSML Docs

Advanced tips:

🔌1. Integrate with External TTS Service Provider

To further enhance the diversity and realism of voices, ReachOut.AI allows you to import additional voices from major external providers. Some popular providers known for their realistic voices include ElevenLabs,, Fliki,, and more. Soon, we will also integrate with and Lovo to provide even more flexibility. To access these additional voices, simply go to the Integrations section and follow the instructions.

🔉2. Upload and Use Real Audio File

For a truly authentic experience, you have the option to import and use your own real voice by uploading an audio file. ReachOut.AI also enables you to synchronize the audio file with the avatars, ensuring a perfect match between the speech and the avatar's lip movements.

Click the voice icon below the editor
Go to "Upload your own voice"
Upload an mp3 or wav file

🎤3. Clone Your Voice with ReachOut.AI

An exciting feature of ReachOut.AI is the ability to clone your own voice, or any other voice. Our voice cloning system can reproduce the tonality and nuances of a voice using just 30 seconds of voice data. This means you can achieve a highly personalized and realistic voice without relying on external providers.

Go to the "Video Personalization" step inside your campaign
Click the Video Dubbing tab
Upload a video of yourself talking or anyone with their consent.
The voice will be cloned and be available under "Cloned voices" popup

📹5. Consider Video Dubbing vs. Digital Human

If you only need to change a variable or two in your content, consider using video dubbing instead of full text-to-videoconversion. Video dubbing can provide a 100% realistic result by synchronizing the changed variables with an existing video.
