Summary

This robot voice generator lets you type a line and preview it as a pause-tagged transcript across five presets: Vocoder Bot, Monotone Synth, Glitch Stutter, 8-bit Quantize, and Deep Drone. Each preset carries fixed pitch shift and formant numbers you would dial into a TTS engine or vocoder chain, while the intensity slider only changes pause density and, on Glitch Stutter, syllable-repeat frequency. Built for game audio devs blocking out NPC dialogue and audiobook producers checking a robotic character read before a full render, no audio file, no external API call, just the tagged script.

Robot Voice Generator: Preview 5 Robotic Delivery Styles

Type a line, pick a preset, and get a pause-tagged transcript with the pitch, formant, and pacing numbers behind it, no audio render required to check the read.

Robot voice generator

Pick a preset, type a line, and adjust intensity. The output is a pause-tagged transcript, not an audio file. Nothing leaves your browser except an anonymous run beacon.

Up to 600 characters. This is the line you would drop into a TTS engine or a VO session sheet.

Scales pause density (and stutter frequency on Glitch Stutter) only. Pitch and formant numbers stay fixed per preset.

How it works

What each preset actually changes

Fixed acoustic signature per preset

Each preset carries its own pitch shift and formant shift. Vocoder Bot runs +2 semitones with formant cut 30%, Deep Drone runs -8 semitones with formant boosted 10%. These are the starting numbers you would punch into a vocoder plugin or a TTS engine's pitch tag.

Intensity scales pause density only

The slider changes how often a pause tag lands, from every 2 words at 100% down to the preset's baseline interval at 0%, and on Glitch Stutter it also raises how often a syllable repeats. It never touches the pitch or formant numbers, so the acoustic identity stays predictable.

Output is a script, not a render

You get a tagged transcript like [pause 120ms], the same marker format you would convert into an SSML break tag or read off during a voice session. No audio is generated and nothing beyond an anonymous run counter leaves your browser.

Questions from the session

Does the [pause Xms] tag match the SSML <break> syntax my TTS engine expects?
Not directly. It is a plain-text placeholder you convert by hand: [pause 120ms] becomes <break time="120ms"/> in most SSML-compatible engines, including Amazon Polly, Azure Speech, and AnyVoice's own API. Plain text keeps the line easy to paste into a script doc or a session sheet.
Why does Glitch Stutter skip short words like 'the' or 'and'?
The stutter only applies to words with 4 or more core letters, punctuation stripped before the check. Function words under 4 letters would sound like random glitching instead of a corrupted transmission, so they are excluded by design.
Can I run 300 NPC lines through this at once?
No, this previews one line at a time in the browser. It is a scoping tool for picking the right preset before you commit a batch to your TTS pipeline or a full recording session, not a batch processor.
Does moving the intensity slider change the pitch or formant shift?
No. Pitch and formant numbers stay fixed per preset, so the spec you read off the panel is accurate regardless of slider position. Intensity only adjusts pause frequency and, on Glitch Stutter, syllable-repeat frequency.
Where does the 150 wpm baseline for estimated pacing come from?
150 words per minute is the narration pace commonly cited in audiobook production guidelines, with ACX-style deliverables landing between 150 and 160 wpm. Each preset applies its own pacing multiplier to that baseline: Deep Drone runs at 0.6x for a slower mechanical read.
Is any audio actually generated here?
No. The tool outputs text only, a tagged transcript computed in your browser. There is no TTS render, no audio file, and no external API call: the whole calculation runs client-side.
Which preset reads closest to a PA announcement versus a heavy industrial unit?
Vocoder Bot (+2 st, formant -30%) reads like a comms-channel PA voice. Deep Drone (-8 st, formant +10%, 300ms pauses) reads like a slow, oversized industrial unit. Monotone Synth sits between the two for a calm onboard-computer read.
Does the tool store or send my script text anywhere?
No. The transcript is computed entirely in your browser and the text you type is never sent to a server. The only network call is an anonymous tool-run beacon that records a page view, not the content itself.
