Eminem's fastest verse vs Smallest Pulse STT

The last verse of "Godzilla" is one of the fastest in mainstream rap. Pulse kept up with all of it: 296 words, 1.4% word error rate.

Just the raw audio, transcribed live.

If Pulse can handle Eminem, your customer calls are easy.

The world's hardest tongue twisters vs Smallest Lightning TTS

In an MIT study, "pad kid poured curd pulled cod" broke volunteers so badly that some just went silent.

We gave it to Lightning v3.1 Pro. Then we made it harder, with 8 more tongue twisters, a switch to Hindi, and the speed pushed to 2x.

Comment the tongue twister you want Lightning to try next.

@anardooo Yes, fully editable right on your timeline.

Editing takes skill. Captioning takes hours.

Capkit by Smallest AI takes the Captioning one off your plate. Click Generate and animated captions land on your Premiere Pro or After Effects timeline.

It runs on Pulse, the fastest speech to text model in the world, so the wait between Generate and captions on the timeline is barely a wait. 20+ languages, Hinglish included.

Pulse STT has the lowest hallucination rate during silence.

A caller goes quiet for eight seconds while looking for their card. Some STT models start filling that silence with words nobody said.

Sometimes, those made-up words can take the entire conversation in the wrong direction.

On audio with multiple silent gaps, Pulse recorded 6.85% WER, compared to 14.03% for Deepgram Nova 3 and 40.39% for ElevenLabs Scribe.

Test Pulse on your own recordings with long pauses. Link in the first reply.

Lightning is the best TTS model for Hindi customer support in Voice Arena’s blind human evaluations.

In the demo below, a customer has received his new card, but it has sat unused because he has not activated it.

An AI voice agent calls him. The call begins in English, then switches to Hindi as soon as he responds. It patiently walks him through the steps.

Those same instructions can sound like a pushy sales call or like someone genuinely trying to help.

Wait for the moment he asks for a minute. That is the difference between a call that delivers instructions and one that delivers support.

Lightning v3.1 Pro is the best real-time TTS model for Hindi customer support on Voice Arena’s blind human evaluations. Try Lightning v3.1 Pro: https://t.co/WHaxWuvD30

@kamath_sutra Lightning would never do you like that, boss man

[smallest.ai @smallest_AI]

Some names need more than a model’s best guess. The pronunciation dictionary lets you define how specific words should be spoken, in plain words, and reuse those pronunciations across calls.

Try Lightning v3.1 Pro with your own names and brands:

[smallest.ai @smallest_AI]

AI voice agents have one problem.

The voice can sound natural, but names and company names are often where they stumble first.

A model that hasn’t encountered a name before may mispronounce it based on its spelling. Callers notice, and one mispronounced name can make the entire interaction feel less human.

Lightning v3.1 Pro is built for names, brands and acronyms, with a pronunciation dictionary for the hardest ones.
