We’re happy to announce a new addition to the functionality of LALAL.AI Voice Changer: the accent and tonality settings. Now you’ve got more control over the end result than ever before! Change the accent, the tonality, or both, depending on your creative vision. 

Be sure to check out the audio examples at the end of this article. They showcase the incredible difference that accent and tonality can make, revealing the complexity of the voice-changing process and how transformative these settings really are.

What’s New? Accent and Tonality Settings Explained

With the new accent and tonality settings, you can now independently adjust two key aspects of your transformed voice:

• Accent. Change how you pronounce words, matching the specific accent of the artist you want to emulate. Want to sound like a British singer or a Southern rapper? Now you can!
• Tonality. With Voice Changer, you can intelligently modify the pitch of both the voice and the instrumental composition to match the target vocal best.

Where to Find the Accent & Tonality Settings

You can change the accent and tonality before you upload a track and during the preview stage. Follow the simple steps below to access the new settings.

The Science Behind Voice Transformation

The human voice is a complex instrument, and several physiological and acoustic factors contribute to how we sound. For a believable voice transformation, we need to capture the unique vocal features of the target voice. This is achieved by changing not only the sound of the voice but also the articulatory characteristics and speech patterns.

🗣️Articulatory characteristics

Articulation refers to how we shape sounds into recognizable speech. This involves the movement of various parts of the vocal tract, including the tongue, lips, and soft palate. Each person has a unique way of articulating sounds, influenced by their accent, language, and personal speech habits.

The new accent change feature allows you to mimic the speech pattern of the target voice. By altering how sounds are produced, you can effectively change the accent of your voice. It plays a big part in creating a convincing transformation, as accents are deeply rooted in the way we articulate words.

For example, a singer might want to give their voice a charming French accent to add a touch of international flair. All they need to do is take a vocal track in their native language, select a French artist’s voice pack, turn the accent change feature on, and voilà—a delightful twist is magically added to the original piece, giving it a unique character.

💬Tonal characteristics

Tonality modification involves altering the pitch, emotional tone, and inflections of a voice, allowing users to change their vocal delivery to match the desired voice. This is what the new tonality change feature helps you to do—capture the essence of the target voice.

For instance, a singer might want to adopt a voice that has a more soulful tone or a playful pitch. They can upload their vocal track, select the target voice, enable tonality matching in the Voice Changer settings, and get back vocals with the desired sound. Without this tonality change, the transformation would feel less authentic and wouldn’t resemble the target voice as closely.

This hybrid approach, which modifies multiple aspects of voice and speech simultaneously, significantly enhances the realism of the resulting voice.

A Comprehensive Voice Transformation Solution

LALAL.AI Voice Changer is powered by a comprehensive neural network system. The voice-shifting network works together with complementary technologies, such as vocal separation, instrumental isolation, echo and reverb removal, and voice cleaning. This allows us to achieve more accurate and natural-sounding voice transformations compared to services that rely on a single neural network.

What's more, the Voice Changer is adaptable to different types of content. Unlike many voice changers on the market, our solution works with everything from clean vocal tracks to mixed songs to voice recordings with background noise. The advanced neural networks can handle various scenarios, providing high-quality voice transformations in each case.

You can upload audio and video files in various formats and languages. LALAL.AI Voice Cleaner supports MP3, OGG, WAV, FLAC, AVI, MP4, MKV, AIFF, and AAC and speaks your language! The underlying technology employs advanced AI voice cloning for seamless cross-language conversions, giving you the power to re-sing songs in various accents. 

For example, you can take a French song and make our AI re-sing it with the accent of an English-speaking person. Our technology ensures that the resulting audio retains the authentic accent and articulation nuances that would be present if the original song had been sung by an English-speaking vocalist.

With the new settings, you are free to use the Voice Changer to alter different aspects of voice together or separately, depending on your goals. Whether you want to preserve some of the original vocal characteristics or transform the voice completely, the tonality and accent settings let you control the level of voice modification.

Audio Examples: Hear the Difference

One of the most effective ways to test the relevance and efficiency of something is to see how things function without it. In this case, we’ll demonstrate what happens if you don’t perform tonality matching or do so without considering all the critical nuances.

We selected a random song and changed the original vocals to match the voice of one of the LALAL.AI team members under different conditions.

📌What happens when you change the voice without matching the tonality

Tonality is a key characteristic that defines an artist's unique vocal signature. Lack of tonality matching causes the altered voice to sound unnatural and not truly representative of the target voice. 

To truly feel the difference, listen to this example of voice transformation without matching the tonality to the target voice. We’ve taken a voice recording and changed it without shifting the tonality.

Changed voice without tonality matching

This audio demonstrates what happens when you change the voice without applying tonality matching.

Sounds kind of jarring, doesn’t it? The lack of tonality matching causes the altered voice to sound unnatural and not truly representative of the target voice.

📌What happens when tonality matching is done for vocals only

Many services excel at altering the vocals themselves but often fall short when it comes to adjusting the instrumental tonality to match the intended voice. As a result, after uploading a song (rather than an a cappella version), you risk receiving a similar outcome:

The voice and instrumental are interdependent; if one is modified without the other, it can create an awkward contrast where the voice feels separate from the instrumental rather than blending seamlessly together.

📌When you change the tonality of the instrumental with the drums

Another widespread problem is when voice changers transform the entire song, not just the vocals alone, but do so including all instruments, even percussion.

Drums don't need to be changed when altering a song's tonality because they're inherently inharmonic, their pitch is often not perceptible, and their primary function is rhythmic rather than melodic. 

Performing tonality matching for drums frequently leads to unpleasant sonic effects. They may resemble slapping or simply sound wobbly, like so:

The bottom line is that tonality matching is the secret sauce that brings it all together. When you get it right, the new vocals melt into the original track like butter on hot toast.

LALAL.AI Voice Changer definitely gets it right, so go ahead, apply the new settings to your songs, and experience the power of high-quality voice transformation!
