La Sintesi turns every phone call into a transcript, an outcome, an agent score, and a metrics dashboard — under sixty seconds, behind a single API.
No credit card. Credits never expire.
“We have hundreds of calls a day — there's no way to listen to them all.”
“We don't know which agents are performing and which aren't until it's too late.”
“We're manually classifying call outcomes in spreadsheets. It's a disaster.”
QA DIRECTOR · CALL OPERATIONS
Submit a recording. Wait under a minute. Get back a fully structured call record — the same one your team will query through the dashboard or your own tools.
Diarized · word-level timestamps · confidence
Speaker-labeled transcript with per-word confidence and offsets. Agent and customer turns are separated automatically.
6 default categories · fully editable per workspace
Every call is bucketed into a business outcome — Successful, Follow-up, Unsuccessful, Negative, No Contact, Informational. Or define your own taxonomy.
Opening · discussion · concerns · outcome
A short, factual recap of what actually happened on the call. No fluff. No invented context.
1–5 · coaching remarks per call
One strength, one improvement area — two improvements when the score is three or below. Built for QA review, not vanity metrics.
Talk time · silence · interruptions · WPM
Per-speaker numbers you can act on. Roll them up across an agent, a team, or a whole operation.
Transcript, outcome, summary, score, and metrics — delivered as one call record over REST. No glue code, no scraping.
Customer called to renew an expiring policy. The agent confirmed coverage, answered two billing questions, and processed a 12-month renewal. No escalation needed.
Clear, unprompted pricing breakdown.
Confirm the callback number earlier.
The default 6-category taxonomy is an industry-neutral starting point. Rewrite it for your business — inbound support, sales, fundraising, real-estate leads, debt collection — and the scoring logic adapts to your taxonomy automatically.
Per-speaker minutes and percentage of the call. See who actually drove the conversation.
Dead air, hold time, and pauses longer than 1.5s — tallied and surfaced per call.
Counted per side. Agent over customer, and vice versa. A small number with a big QA story.
Speaking pace per speaker — and how it shifts mid-call when the conversation turns.
Most teams weigh the same three options. Here's the honest trade-off — no straw men.
◎ NO SALES CALL · NO CONTRACT · LIVE IN UNDER A MINUTE
$0.05 / MIN · CREDITS NEVER EXPIRE
Billed per started minute — a 3:01 call counts as 4 minutes, same as every telecom you've ever used. Calls under a minute count as one. Re-viewing analysis is always free; re-running the AI on a call is free for the first 2 attempts, then $0.03 flat each.
These are prepaid credit packs, not subscription tiers — same $0.05/minute on every one. No seats, no minimums, no contract. Pick the balance that fits your volume and top up when it runs low; credits never expire.
Most teams land here — about a month of steady volume in one top-up.
