How To Create High-Quality Voice Overs For YouTube Using FREE AI Tools

If you want to create high-quality voiceovers for your YouTube videos, but don't have the budget or the skills to record your voice, you might be interested in using free AI tools that can generate realistic and natural-sounding voices from text.

In this blog post, I will show you how to use some of the best free AI tools for voice-over creation, and how to optimize your text for better results. Before delving into the tools, it's crucial to understand the implications of using AI-generated voiceovers on YouTube monetization.

While AI-generated voices can be a powerful asset, there's a fine line between a human-like voice and a robotic one. YouTube's algorithms favor content with natural-sounding voices, and overly robotic voices can lead to demonetization.

Microsoft Azure Text-to-Speech

The first tool I recommend is Microsoft Azure Text to Speech, which is a cloud-based service that can convert text to speech in over 200 languages and dialects. You can choose from a variety of voices, including neural voices that use deep neural networks to produce human-like speech.

You can also customize the voice parameters, such as pitch, rate, volume, and pronunciation. Here are the steps to use Microsoft Azure Text to Speech for generating voiceovers:

1. Create an Azure account and a Speech service subscription. You can start with a free trial that gives you $200 credit and free amounts of many services.
2. Choose a prebuilt neural voice or create a custom neural voice. Prebuilt neural voices are ready-to-use voices that sound natural and realistic. Custom neural voices are unique voices that you can create with your data and style. To choose a prebuilt neural voice, check the Voice Gallery and select the voice that suits your needs.
3. Use the Speech SDK or REST API to convert text to speech. The Speech SDK is a library that lets you integrate speech functionality into your applications. The REST API is a web service that lets you send HTTP requests and receive responses with speech audio.?
4. Save the speech audio as a file or stream it to your device. You can choose the format and quality of the speech audio according to your needs.

?Google Cloud Text-to-Speech

The second tool I suggest is Google Cloud Text-to-Speech, which is another cloud-based service that can synthesize speech from text in over 40 languages and variants. You can also select from different voice types, including standard and WaveNet voices that use advanced neural network techniques to create natural and expressive speech.

You can also adjust the voice features, such as speaking rate, pitch, volume, and emphasis. Here are the steps to use Google Cloud Text-to-Speech for generating voiceovers:

1. Create a Google Cloud account and a Text-to-Speech API service account. You can start with a free trial that gives you $300 credit and free amounts of many services.
2. Choose a prebuilt standard or WaveNet voice or create a custom voice. Prebuilt standard voices are basic synthetic voices that are suitable for simple use cases. Prebuilt WaveNet voices are advanced synthetic voices that sound more natural and realistic. Custom voices are unique voices that you can create with your own data and style. To choose a prebuilt voice, check the Voice List and select the voice that suits your needs.
3. Use the Client Libraries or REST API to convert text to speech. The Client Libraries are libraries that let you integrate speech functionality into your applications. The REST API is a web service that lets you send HTTP requests and receive responses with speech audio.
4. Save the speech audio as a file or stream it to your device. You can choose the format and quality of the speech audio according to your needs.

Amazon Polly

Amazon Polly is another service that can turn text into lifelike speech in over 30 languages and accents. You can choose from a range of voices, including neural voices that leverage deep learning to produce realistic and engaging speech.

You can also modify the voice attributes, such as speed, pitch, volume, and pronunciation. Here are the steps to use Amazon Polly for generating voiceovers:

1. Create an AWS account and an Amazon Polly service role. You can start with a free tier that gives you 5 million characters per month for 12 months.
2. Choose a prebuilt standard or neural voice or create a custom voice. Prebuilt standard voices are basic synthetic voices that are suitable for simple use cases. Prebuilt neural voices are advanced synthetic voices that sound more natural and realistic. Custom voices are unique voices that you can create with your data and style. To choose a prebuilt voice, check the Voice List and select the voice that suits your needs.
3. Use the AWS CLI or the Amazon Polly console to convert text to speech. The AWS CLI is a command-line tool that lets you interact with AWS services. The Amazon Polly console is a web-based interface that lets you enter text and listen to the speech output.?
4. Save the speech audio as a file or stream it to your device. You can choose the format and quality of the speech audio according to your needs.

?Murph AI

Another go-to solution for free, high-quality AI-generated voiceovers is Murph.ai. With a user-friendly interface and a range of voices to choose from, Murph.ai is a valuable tool for content creators.

3. Name your project, such as "Story Brand Review," and choose to upload later since we're focusing on creating the voiceover.

Step 2: Choosing Your AI Voice

1. Click on the "Voices" tab, where you'll find a variety of AI voices to choose from. For example, select "Adam."
2. Add your script to the workspace. Murph.ai automatically organizes each sentence on a separate line for your convenience.

Step 3: Building Your Audio

1. Click on "Build Audio" to generate the AI voiceover based on your script.
2. Murph.ai quickly processes the audio, and you can preview the result by clicking "Play."

Step 4: Adjusting Settings

1. Experiment with different voices, speeds, volumes, and pronunciations to customize your voiceover.
2. Keep in mind that a more human-like voice is crucial for YouTube monetization.

Step 5: Recording the Voiceover

1. Once satisfied with the voiceover, use a free recorder to capture the audio. You can use built-in recorders on your computer or consider free online options.
2. Start the recorder and play the AI-generated voiceover on Murph.ai. Save the recording to your desired location.

Step 6: Adding Background Music (Optional)

1. If you wish to enhance your voiceover with background music, upload your chosen soundtrack on Murph.ai.
2. Click on "Build Audio" again to combine the AI voiceover with the background music. Adjust volume levels if necessary.

Step 7: Repeat for Additional Segments

1. To create a comprehensive voiceover for your entire video, repeat the process by adding new paragraphs to Murph.ai.
2. Record each segment separately using the free recorder.

Step 8: Assembling the Final Voiceover

1. Use a free desktop audio recorder to combine and edit the recorded segments into a cohesive voiceover.
2. Ensure that the audio levels are consistent, and there are no abrupt transitions between segments.

Step 9: Save and Export

1. Once satisfied with your final voiceover, save the recording in your preferred audio format.
