01 / STT — Speech → Text
An acoustic model trained separately for Turkish. It holds accuracy on noisy lines, through accents and half-finished sentences, streaming while the other person is still speaking.

Technology and security
We own all three models: the one that turns speech into text, the one that decides, and the one that speaks. Because we depend on no outside API, we control the latency and can install the whole stack on your own servers.
Core technology
All three links in the chain are ours.
02 / LLM — Understanding → Decision
Fine-tuned on your data, pricing policy and scenarios. It reads intent, recognises objections and reaches into your CRM, calendar or payment system when needed.
03 / TTS — Text → Voice
A natural, on-brand voice. It stops when interrupted and shifts emphasis when asking a question. This is exactly what decides how many people hang up.
480 ms end to end
Hearing, understanding and answering stays inside the rhythm of human conversation. Nobody waits for the other side to think.
Turkish first
The models were trained on Turkish speech. Idioms, inverted sentences and the way prices and dates are read are native, not a bolted-on translation layer.
Your vocabulary
Product names, campaigns, discount limits and promises that must never be made are taught per organisation. The model improves as it is used.
Deployment
You decide where the system runs.
The same AI, three different homes. Choose by regulation and IT preference — and move later if you need to.
Callser Cloud
On infrastructure we manage, paid by usage. Setup, scaling and updates are on us.
- First calls within days
- Automatic updates and redundancy
- Elastic capacity for campaigns
- Processing in a Turkish location
Turkish-resident cloud
Audio, recordings and transcripts are processed and stored only in data centres inside Turkey.
- Data residency in Turkey
- Isolated, dedicated environment
- Full KVKK compliance
- Immutable audit trail
On your own servers
The models run in your data centre, on your hardware. Without an internet connection if you want.
- Your list never leaves the building
- Air-gapped option
- Enterprise SSO and role-based access
- On-site installation and maintenance
Security and compliance
In a system that makes calls, compliance cannot be retrofitted.
Outbound carries a different duty of care than inbound: consent, calling hours and recording rules have to be right from the start. We built the architecture around that — and around one more rule: the data stays with the organisation.
- Consent and İYS. Consent checks, no dialling of records without permission, immediate opt-out processing.
- Disclosure and transparency. Callers are told at the start; anyone who asks is transferred to a person immediately.
- Data residency. Your list, recordings and transcripts never cross the boundary you choose.
- Data minimisation. Only required fields are processed, and data is deleted when retention expires.
- Encryption and access. Encrypted in transit and at rest; role-based access, SSO and immutable audit logs.
- Contracts and testing. Data processor agreement, VERBİS support and independent penetration testing on request.
