Hear Alex on real scripts
Each clip below was generated with a free-tier voice on the script shown. Play one to hear how this kind of writing lands, or load the script into the generator above and hear Alex read it.
Short-form story
Narration for a faceless story clip, built to land in under a minute.
“So my neighbour knocks on the door at eleven at night holding a ladder. Not asking for anything — just holding it. And he says, completely calmly: don't worry, this is about the cat. It was not about the cat.”
Stream alert
A donation or follow alert that reads cleanly over game audio.
“New follower — welcome in. And a five-dollar tip from the back of the chat with the message: lose the pickaxe, use the torch. That is a genuinely good note and I am ignoring it completely.”
Server announcement
Short spoken notice for a Discord or community channel.
“Quick one, everyone. The game night moved to Saturday at eight, the invite link in the pinned message still works, and whoever keeps renaming the voice channel — we know it's you, and it's very funny, please stop.”
About the Alex voice
Alex is the clear, unfussy Spanish male voice — plainer than Dora and better for material where the content is doing the work. He is a good default for instructional Spanish, and for anything where you would rather the listener remembered the point than the reading.
Why a Spanish voice, and not an English one
Alex was trained on Spanish, which matters more than it sounds like it should. An English voice pointed at Spanish text will get the individual sounds roughly right and the rhythm completely wrong — stress in the wrong places, vowel lengths flattened, the melody of the sentence replaced with an English one. It is intelligible and it is immediately, unmistakably foreign.
Spanish is also read here by Dora — worth previewing side by side, since the difference between two voices in the same language is usually more useful than the difference between two languages.
The engine behind this voice
Kokoro is an 82-million-parameter open-weights model under Apache-2.0 — the cheapest capable engine available by roughly an order of magnitude, which is what makes this tier free at all. It takes up to 5,000 characters per request, adjusts from 0.75× to 1.5×, and returns MP3 or WAV. Longer text is split at sentence boundaries and joined back into one file.
More about Kokoro TTS →What Alex costs
Nothing. Alex is a free-tier voice: 5,000 characters a day without an account, 10,000 with a free one, and no credit card at any point. Audio downloads as MP3 or WAV and carries a commercial licence, so monetised videos and client work are both fine.
The daily allowance is stated plainly here because several sites in this category advertise "unlimited" and enforce a monthly cap. What is written above is what the server enforces.
Best for
What Alex is good for
- Spanish tutorials, instructions and technical explanation
- Announcements, notices and information lines in Spanish
- Longer Spanish narration where an expressive read would tire
- Male-voice Spanish content paired with Dora for dialogue
Limits
Where Alex is the wrong choice
Plain is the point and also the limitation: on anything requiring warmth or persuasion he reads as an announcement. Use Dora where the listener has to feel something.
