Setting Up TTS: A Guide for Vtubers

Have you ever wondered how virtual YouTubers create their unique voices? In this guide, I will walk you through the process of setting up Text-to-Speech (TTS) for your own VTuber persona. Whether you want to add a touch of uniqueness or you are unable to use your own voice, TTS can help you bring your virtual character to life. So, let's dive in and explore the various steps involved in setting up TTS for your VTuber persona.

1. Introduction

Virtual YouTubers, or VTubers for short, have gained popularity in recent years. One of the key elements that make VTubers stand out is their distinctive voices. While some VTubers may have their voices provided by human voice actors, others rely on TTS technology to create their virtual personas. In this guide, we will focus on the latter approach and explore the process of setting up TTS for your VTuber persona.

2. Setting up the Audio Settings

The first step in setting up TTS for your VTuber persona is configuring the audio settings. One essential tool for this purpose is Voicemeeter Banana. By using Voicemeeter Banana, you can create a virtual input and output that acts as a microphone. This is crucial because it allows you to redirect the audio from your TTS application through this virtual audio cable.

3. Choosing the Right Voice App

When it comes to selecting the right voice app for your VTuber persona, VRChat Speech-to-Text (VRCSDT) is a popular choice. Originally designed for VRChat players, VRCSDT can also be used by TTS tubers. It offers features like voice customization, translation capabilities, and a wide range of languages and voices to choose from. It is important to note that VRCSDT requires a Patreon subscription to cover the costs of Amazon Web Services (AWS) and Microsoft Azure, which the app relies on for Transcription and output.

4. Using VRCSDT for TTS

With VRCSDT, you can unleash your creativity and experiment with different voices and languages. The app allows you to type your desired text, which is then transformed into TTS speech. Additionally, you can even use a microphone to speak, and VRCSDT will transcribe your words and output them as TTS voices. This opens up a world of possibilities for TTS tubers who want to create unique content in different languages and voices.

5. Subscription Costs and Benefits

To unlock the full potential of VRCSDT, it is recommended to subscribe to one of the premium tiers. While this comes at a cost, the benefits are well worth it. The highest tier grants you access to features like speech-to-text-to-speech and continuous listening. This means that not only can you type in text for TTS output, but you can also speak into a microphone and have your words transcribed and transformed into TTS voices. Additionally, your subscription helps support the developers in maintaining and improving the app.

6. Translating and Multilingual Capabilities

One of the remarkable features of VRCSDT is its ability to Translate text and support multiple languages. This means that you can speak or type in one language and have the app translate it into another language of your choice. This functionality adds a whole new dimension to your content creation, allowing you to reach a broader audience and engage with viewers from different linguistic backgrounds.

7. Creating a Virtual Microphone Input

Once you have your virtual audio cables set up and your TTS application ready, the next step is to configure your streaming software, such as OBS, to recognize the virtual audio cable as a microphone input. By setting the output of the virtual audio cable as the microphone input in OBS, you can ensure that the TTS speech is captured and broadcasted during your streams. Remember to enable audio monitoring so that you can hear the TTS speech in real-time.

8. Incorporating TTS with OBS

OBS is a widely used streaming software that seamlessly integrates with VRCSDT and other TTS applications. With OBS, you can capture the TTS audio and include it in your streams. It is recommended to adjust the OBS settings to prevent broadcasting desktop audio and instead focus on capturing audio from specific sources. By doing so, you can ensure that unwanted sounds and system notifications are not inadvertently shared with your viewers.

9. Adding Subtitles with VRCSDT and OBS

Enhance the accessibility of your streams by adding subtitles to the TTS speech. VRCSDT offers logging functionality that creates a text file containing all the words spoken by the TTS. OBS can then be configured to display this text file as a text source overlay in your streams. By enabling subtitles, you make your content more inclusive and provide an additional means of engaging with viewers who may prefer or require written text.

10. Using VTube Studio with Virtual Audio Output

If you are using VTube Studio for your VTuber model, you can leverage the virtual audio output feature to make your TTS speech seamlessly integrate with your virtual avatar. By setting the virtual audio output as a microphone input in VTube Studio, you can synchronize the TTS speech with the movements of your avatar's mouth. Fine-tuning the settings allows for better Lip Sync, resulting in a more immersive and realistic streaming experience.
