Who does what
We build it. It talks. You set the rules.
Our engineers stand VoxSphere up and wire it into your systems. The agents handle the conversations, and your business users shape how they behave.
01
Comprinno delivers
Our team deploys VoxSphere in your AWS account and sets up the integrations, agent workflows and rollout included in your engagement.
02
VoxSphere runs the conversations
The platform handles real-time calls, grounds answers in your knowledge, escalates when needed and captures post-call analytics.
03
Your team sets the rules
Business users configure personas, workflows and negotiation boundaries, manage knowledge documents and review call analytics.
Agentic capabilities
Agents that act, not just answer.
Scripted bots answer questions. VoxSphere agents negotiate, retry, escalate and drive multistep workflows toward an outcome.
Workflow orchestration
Multistep conversation flows with conditional branching, tool calls, automated escalation and agent handover, from first contact through resolution.
Context-aware negotiation
Agents adapt tone, offers and strategy in real time, based on conversation signals and customer history.
Smart nudges
Timely prompts that guide outcomes, such as payment commitments, confirmations and upsells.
Retry optimization
Works out the best retry timing, channel and approach from earlier interaction outcomes.
Automated outbound workflows
Scheduling, sequencing and follow-up for outbound campaigns at scale.
Human-in-the-loop
Escalation to a human agent with full context, plus configurable review checkpoints.
Guardrails and audit trail
Compliance boundaries enforced in real time, with every agent decision logged for governance.
Evaluation framework
Conversation scoring, A/B tests across personas and scripts, and drift detection for continuous improvement.
Inside VoxSphere
Built for real calls, end to end on AWS.
A serverless platform that scales from a single call to hundreds of concurrent calls, with telephony-grade latency.
01 · Dashboards and analytics
See how every call performs.
- Business dashboards for call volume, latency and quality
- Post-call analytics with summaries and keyword extraction
- Every conversation turn, tool call and agent decision logged to Amazon CloudWatch
02 · Two voice pipelines
Pick the pipeline that fits the call.
- Unified speech-to-speech: Amazon Nova Sonic 2 listens, reasons and speaks in one bidirectional stream, in Hindi and English
- Modular pipeline: Deepgram Nova-3, Amazon Nova 2 Lite and ElevenLabs Flash 3 as separate stages, for more languages and mid-call language switching
- Both share the same knowledge base, tools, memory, guardrails and configuration
03 · Self-service configuration
Launch new use cases without rebuilding.
- Configure agent personas, workflows and negotiation boundaries
- Upload knowledge documents; ingestion keeps answers current
- Natural turn-taking with barge-in handling and filler-word filtering
Built on
Engagement and rollout
From use case to live calls.
Start with the calls you want to automate. Define the scope, deploy in your account and roll out with measures you agree up front.
Assess
Review your use case, call types, volumes, languages and the systems agents need to reach.
Agree
Define scope, integrations, guardrails, escalation paths, access and success measures.
Deploy and configure
Deploy in your AWS account, connect telephony and business systems, load knowledge and set up personas.
Go live and improve
Launch on agreed call flows, then use scoring, A/B tests and post-call analytics to keep improving.
Built by the team that deploys it.
The AI and cloud engineers who designed VoxSphere on AWS are the ones who roll it out for you. You know from day one who answers when something needs attention.
Got more call types in mind? Add them as new use cases once the first one is live.
Security and control
Your account. Your data. Your rules.
Calls, transcripts and knowledge never leave your AWS account. You decide what our engineers can reach and which changes need your sign-off.
Hosted in your AWS account
The whole platform runs inside your own AWS account, so your data stays in your environment.
Isolated and encrypted
Each business unit or tenant keeps its documents and knowledge separate, and data is encrypted at rest with AWS KMS.
PII handling
Personal information in calls and transcripts is handled with dedicated safeguards.
Guardrails and full observability
Compliance boundaries are enforced in real time, and every turn, tool call and decision is logged.

Before you pick up the phone.
What buyers usually ask about voice agents, languages and data.
What is VoxSphere?
VoxSphere is a platform for real-time, multilingual AI voice agents. It runs serverless in your AWS account, grounds answers in your own knowledge and handles post-sales support and outbound calls.
What does Comprinno do in a VoxSphere engagement?
Comprinno deploys VoxSphere in your AWS account and sets up the integrations, agent workflows and rollout included in your engagement. Support and escalation paths are agreed up front.
Can it handle both inbound and outbound calls?
Yes. Agents handle inbound post-sales support and run outbound campaigns with scheduling, sequencing, follow-up and retry optimization.
Which languages does it support?
The unified speech-to-speech pipeline supports Hindi and English. The modular pipeline adds more languages and mid-call language switching.
Where do the answers come from?
From the knowledge documents you upload, through Amazon Bedrock Knowledge Bases. Automated ingestion keeps answers current as documents change.
What happens when a call needs a person?
The agent escalates to a human agent with the full conversation context. You can also configure review checkpoints.
Where is my data stored, and who can access it?
In your own AWS account. Data is isolated per business unit or tenant and encrypted at rest with AWS KMS. The access Comprinno needs is defined as part of the engagement.
How are platform, service and AWS charges handled?
Platform and Comprinno service fees are defined in your engagement. AWS usage runs in your account and is billed by AWS at its standard rates.
