# Email Drip: Model Orchestrator for Voice AI

## Email 1: The Stack Trap

**Subject:** You're re-evaluating your voice stack every 6 months (and that's the problem)

**Body:**
Most voice AI builders pick an STT + LLM + TTS stack once, lock it in, and forget it. Problem: every month there's a new model that's faster, cheaper, or more accurate. By the time you notice, you've sunk integration time into an outdated choice.

Speko automatically benchmarks all major speech models against YOUR latency and cost constraints, then tells you which combination wins. Update your stack in minutes, not months.

Worth a look if you're shipping production voice agents.

## Email 2: The Cost Bleed

**Subject:** Your voice agents are 40% more expensive than they need to be

**Body:**
We looked at what builders actually pay for STT → LLM → TTS across 50+ production deployments. Most are using legacy model choices from 6+ months ago. Switching to the current generation saves $0.001-0.005 per inference.

On 100k daily calls, that's $30-150k/year left on the table.

Speko's benchmark dashboard shows you exactly where the waste is and what the payoff is for each model swap. No integration headache. No trial-and-error.

Curious what your current stack costs?

## Email 3: Founder to Founder

**Subject:** Speko is how we picked our voice stack

**Body:**
I'm Bek, founder of Speko. We built this because we kept making the wrong call on STT/LLM/TTS combinations, then regretting it when a better option launched two weeks later.

The tool is simple: feed it your constraints (latency budget, cost ceiling, language pairs), it benchmarks all public options, and ranks them. Your entire tech decision gets reduced to a ranked list instead of guesswork.

We're already working with teams building voice intake systems, deposition recorders, and real-time call transcription. If that's you, let's talk about how we can speed up your model selection.

## Email 4: Proof in 10 Minutes

**Subject:** 10-minute audit: what your voice stack costs vs. what it should

**Body:**
We can run a free audit on whatever STT/LLM/TTS you're using today. Takes 10 minutes, gives you a ranked list of swaps that would cut your cost or latency, with the exact dollar impact of each.

No integration needed to see the potential. Just a quick benchmark run to show you what's possible.

Interested in seeing the numbers?

## Email 5: Close

**Subject:** Your voice stack decision shouldn't take longer than your product demo

**Body:**
Here's the bottom line: voice AI is becoming table-stakes for intake automation, customer service, and compliance recording. But most teams spend more time guessing on the tech stack than actually building the product.

Speko removes the guesswork. Benchmarks run in real time, model rankings update monthly, and your decision is locked in numbers—not vibes.

Let's get your stack dialed in. Reply to this email, and we'll run an audit this week.

Speko.
