How do you make an AI voice sound nasal?
A nasal voice generator adds the pinched, twangy texture comedy writers reach for — the classic nerd-character voice, the congested stuffy-cold delivery, the whiny sidekick who complains through every line. Instead of pinching your own nose in a recording booth, you paste the script, pick a voice, and the texture comes back rendered.
Rather than one "nasal filter" slider, Notevibes builds the effect from cadence and emotion tags working together. [nervous] and [excited] give the quick, precise delivery that reads as nerdy; [tired], [sighs], and [trembling] give the congested, self-pitying quality of a stuffy cold; [bored] stretched over a complaint gives the whiny-sidekick drawl. The pinch comes from the writing and pacing as much as any single tag.
Getting the pinch right
Nerdy Twang and Know-It-All both lean on [mischievously], [cheerful], and [excited] with short, precise phrases and a dash on the correction — "Actually —". Stuffy Cold and Whiny Sidekick go the opposite direction: [tired], [sighs], and [trembling] slow things down and add self-pity, while [bored] paired with elongated vowels ("wannaaaa") sells the sidekick whine.
Voice choice matters as much as the tags. Algenib carries the pinched nerd quality naturally, Puck handles stuffy-cold and sidekick whine well, and Enceladus is built for elongated whiny-character complaints.
Where this voice gets used
Animators reach for it for classic-nerd sidekicks and comic-relief characters, and game developers use the same tags for nerd-archetype NPCs, know-it-all quest-givers, and allergy-stricken townsfolk. Comedians use the stuffy-cold register for sick-day bits, and ad creators use it for cold-and-flu product spots that need an authentic-sounding stuffed nose.
Podcasters use nasal-character voices for comedy sketches and impressions, and audiobook authors drop it in for nerdy secondary characters in comedy fiction — the four demo scripts on this page (nerdy twang, stuffy cold, whiny sidekick, know-it-all) map directly onto those use cases.
Publishing and pairing with other voices
Preview any generation before downloading, then export MP3 or WAV with no watermark. Paid plans include full commercial rights, covering animation, commercials, games, and audiobook character work.
If nasal is too narrow a slice of the character you are writing, pair it with the broader nerd voice generator — nasal is the texture, nerd is the fuller archetype — and the same 72-language support carries both.

Frequently Asked Questions
How do I make the AI sound nasal?
Pair voices like Algenib or Puck with [nervous] + [excited] tags and write in short precise phrases. The cadence drives perceived nasality even without an explicit pinch.
Which voices sound the most nasal?
Algenib has the pinched nerd quality built in. Puck handles stuffy-cold and whiny sidekick well. Enceladus delivers elongated whiny-character complaints.
Can the AI do a congested stuffy-cold voice?
Yes. Pair [tired] + [sighs] + [nervous] across sick-day phrasing for that authentic congested delivery. Great for cold-and-flu product ads or sick-day comedy.
Can I use nasal voices for commercial animation?
Yes. Full commercial rights on paid plans cover animation, commercials, games, and audiobook character voices.
How is this different from the nerd voice generator?
Nerd is the broader archetype — smart, socially awkward, hyper-specific. Nasal is specifically the voice texture — pinched, congested, twangy. Use nasal to sharpen the nerd effect.
