## SoundHound AI (Houndify)

SoundHound AI focuses on one hard problem: making conversational agents that still perform when real interactions get messy — background noise, interruptions, accents, and mixed intents. Its platform, OASYS, is described as an orchestrated agent system that is voice-first rather than a text chatbot with speech bolted on. Teams pick agents and models, set permissions and policy controls, choose edge or cloud execution, and plug in human-assisted resolution where automation should hand off to a person.

The company positions the platform around four practical qualities: agents that keep listening through chaotic conditions, deep control via rule-based actions and guardrails, deployment to any digital or physical touchpoint from one system, and flexible co-management so brands can build agents themselves, with AI, or with SoundHound. A commerce ecosystem lets brands connect their agents to devices and services to open new revenue paths.

SoundHound reports more than 10 billion conversations handled annually and cites 20+ years of AI work and 750+ patents across voice and agentic AI. Industries served include automotive (with voice assistants deployed in vehicles from partners such as Stellantis), restaurants (drive-thru and phone ordering, e.g. Five Guys), healthcare, financial services, insurance, telecommunications, travel and hospitality, retail, and utilities. The platform is sold to enterprises and developers; SoundHound does not publish list pricing and instead routes interested teams to a demo and contact conversation.

**Pricing & Plans:** SoundHound AI does not publish public pricing for its conversational AI platform. Commercial terms are enterprise- and volume-based, arranged through a demo request or by contacting the sales team.

- **OASYS orchestrated agent system:** A voice-native platform for building and orchestrating AI agents, with agent and model selection, rule-based actions, and human-assisted resolution.
- **Voice-first accuracy in noisy conditions:** Agents are designed to keep listening and understanding through interruptions, background noise, and the unpredictable flow of real conversations.
- **Control, security, and compliance:** Layered guardrails at instruction, task, function, and channel level, a proprietary PII-detection LLM, tenant isolation, encryption, and full audit logging.
- **Any touchpoint, one platform:** Deploy agents to digital channels and physical locations — phones, drive-thrus, in-car systems, kiosks, and employee tools — from a single system.
- **Cross-industry solutions:** Purpose-built use cases for contact centers, IT service desks, digital assistants, drive-thru, outbound, front desk, HR, and voice commerce.

**Strengths:** Voice-native architecture built for noisy, real-world conversations rather than retrofitted text chat; Deep enterprise controls: guardrails, PII handling, tenant isolation, and audit logging; One platform covering digital and physical touchpoints, including in-car and drive-thru; Backed by a long patent portfolio and large-scale deployment track record

**Limitations:** No public pricing; evaluation requires a sales conversation and demo; Enterprise-oriented onboarding, not a self-serve tool for individuals; Best value comes with integration effort into existing contact center or product stacks

## Synthflow.ai

Synthflow is an enterprise conversational AI platform for phone calls. Its AI voice agents answer inbound calls and place outbound ones on behalf of contact centers, BPOs, multi-location retail brands, healthcare providers and financial services teams. Rather than routing callers into a separate app, the agents work inside the phone system you already run, resolve routine requests such as order problems, appointment booking and callbacks, and update your CRM while the conversation is still happening.

The platform leans on three practical strengths. First, realism: the company says agents reply in under half a second, tolerate interruptions, can switch language mid-call, and hand the caller to a human with a full transcript. Second, integration: agents connect to systems like Salesforce, HubSpot, Zendesk and Freshworks, with built-in support for Zoom, Five9, RingCentral, 8x8, Twilio, Telnyx, Vonage and Freshcaller, plus SIP-compatible carriers. Third, operational control: Synthflow runs its own telephony with regional points of presence, and exposes the SIP ladder, packet capture and quality scores for each call.

Enterprise readiness is a major part of the pitch. Synthflow is SOC 2 Type II audited, ISO/IEC 27001 certified and PCI DSS v4.0.1 compliant, offers a HIPAA BAA and GDPR terms with a DPA, and lets customers pick a US or EU workspace at setup. The site reports 1M+ calls a day handled, 99.99% platform uptime and customers including Freshworks, Thryv and Batteries Plus, with deployment often measured in weeks via forward-deployed engineers.

**Pricing & Plans:** Free trial available with pricing provided on request; the site lists a Pricing page plus a demo path for enterprise scoping. Costs depend on call volume, telephony and integrations, so confirm current plans with the vendor.

- **No-code voice agent builder:** Design AI agents for inbound and outbound calls without building a custom voice stack yourself.
- **Real-time CRM and system updates:** Agents read and write Salesforce, HubSpot, Zendesk, Freshworks and more during the call, through 200+ integrations.
- **Works with your phone system:** Keep your numbers and carrier thanks to built-in connections for Zoom, Five9, RingCentral, 8x8, Twilio, Telnyx, Vonage and Freshcaller, plus SIP setups.
- **Own telephony and call observability:** Synthflow runs regional telephony infrastructure with SIP ladder, packet capture and quality scores for every call.
- **Testing and release controls:** Agents are tested on your own cases, released step by step with your approval, and measured on every call afterwards.

**Strengths:** Voice agents work inside your existing phone system, so numbers and carriers stay; Sub-500 ms responses with interruption handling and language switching; Strong compliance posture (SOC 2 Type II, ISO 27001, PCI DSS, HIPAA BAA, GDPR DPA); Tested on your own calls before launch, with per-call observability after

**Limitations:** Pricing is not fully public and often requires a sales conversation; The deepest integrations and telephony control are aimed at larger deployments; Most value assumes you have an existing phone system and CRM to connect
