Baldi AI voice generator & voice changer

About the Baldi voice

Baldi is the ruler-wielding math teacher from Baldi's Basics in Education and Learning, an indie horror game made to look like a cheap, old-fashioned educational title. Players explore a empty schoolhouse, collect notebooks and try to avoid Baldi, who gets upset when math problems are answered wrong. The character became a widely recognized internet figure through the game's strange mix of cheerful learning-game style and tense chase gameplay, along with plenty of fan videos and memes.

The voice is loud, bright and a little unsettling. Baldi speaks in an upbeat, overly enthusiastic teacher tone that can suddenly turn sharp and shouty. The pitch sits fairly high and nasal, the pace is quick and bouncy, and the delivery is exaggerated, with stretched vowels, stern emphasis and a cheerful menace behind the friendly words. Expect something that sounds like a very excited, slightly angry classroom instructor.

On voicechange.io you can record or upload speech and have it converted into Baldi, type text to hear it spoken in this voice, or make a song cover. The pitch is matched to the voice automatically, so you don't need to adjust it. For best results, speak clearly and energetically, with big emphasis and clear pauses, as if you were announcing a pop quiz. Short, punchy lines work especially well, and a clean recording with no background noise gives the cleanest result.

Voice details

Tips for the best Baldi result

This model is centred around 130 Hz. With auto pitch on, a typical deeper voice (around 120 Hz) isn't shifted, since it already fits, and a typical higher voice (around 210 Hz) is shifted about 8 semitones down. Gaps under 4 semitones are left alone, and shifts stop at one octave. If the result sounds strained, nudge the slider one or two steps back toward your own voice; for song covers, keep it at 0, +12 or −12 so the vocal stays in key. How pitch works.

• Record in a quiet room with no music in the background; noise is the main cause of robotic-sounding results.
• Perform the line the way Baldi would say it. The model copies your timing and emotion, only the voice changes.
• For song covers, pick a track with one clear lead vocal and little reverb.
