It enables you to conduct customer conversations that feel more natural than ever before, with latency under 300 ms that mimics human interaction. Get ready to see how Famulor optimizes your processes, increases customer satisfaction, and gives you a clear competitive edge.

Soniox: Precision and Speed in Speech-to-Text Transcription

The quality of speech recognition is the foundation of any successful AI-driven telephony system. By implementing Soniox as the new Speech-to-Text (STT) provider in Pipeline Mode, Famulor takes a decisive step forward. Soniox delivers enhanced transcription accuracy across a multitude of languages with noticeably lower latency. This means your Famulor Voice Assistants not only understand callers more precisely but also react to their needs faster and more naturally.

Why Soniox Makes a Difference:

• Increased Accuracy: Soniox improves the comprehension of complex speech, dialects, and specialized terminologies, leading to fewer misunderstandings and more effective conversations.
• Lower Latency: The faster processing of spoken language by Soniox ensures a smoother conversational flow. Your AI assistants can respond to callers almost in real-time, making the interaction feel natural and less robotic.
• Multilingual Competence: With improved support for multiple languages, companies can expand their reach globally without compromising on speech recognition quality.

Practical Example:

An international company offering customer service in various countries can use Soniox to ensure that callers are understood precisely in their native language—whether it's German, English, French, or any of the more than 40 languages supported by Famulor. This results in higher customer satisfaction and more efficient handling of inquiries.

How to Enable Soniox in Famulor:

Selecting Soniox as your transcription provider is incredibly easy. Navigate to your Assistant in the Famulor dashboard, choose "Pipeline Mode," and select "Soniox" as the transcription provider. To achieve the best results, we recommend running A/B tests to compare its performance against your previous setup.

GPT Realtime 1.5: The Next Level of Speech-to-Speech for Human Conversations

Speech-to-Speech mode is vital for creating human-like dialogues. With the upgrade to OpenAI's GPT Realtime 1.5, Famulor reaches a new standard of conversational quality. This update brings significant improvements in several key areas, elevating the user experience to unprecedented levels.

The Benefits of GPT Realtime 1.5 at a Glance:

• Better Call Quality: Experience more natural and fluid conversations. Enhanced voice output via Famulor's proprietary engine ensures a more pleasant listening experience.
• Lower Latency: Even faster response times from the AI assistant create a smoother caller experience. Latency can be under 300 ms, which is almost indistinguishable from human reaction times. This low latency is crucial for natural "barge-in" capabilities, allowing callers to interrupt the AI assistant without any delays.
• Improved Prompt Following: The assistant adheres more reliably to the script and processes complex instructions better. This increases precision in handling specific requests and maintaining conversational guidelines.

Practical Example:

A customer calls to urgently reschedule an appointment. With GPT Realtime 1.5, the AI assistant not only instantly grasps the request but also responds fluidly and empathetically while querying the calendar integration and rebooking the appointment in the background. If the customer asks another question in the meantime, the assistant handles it seamlessly without breaking the conversational flow thanks to its low latency.

How to Use GPT Realtime 1.5:

Simply select GPT Realtime 1.5 in the configuration of your assistant under Speech-to-Speech mode. You can also leverage Famulor's No-Code Flow Builder to optimally design conversational flows for barge-in scenarios, enabling even more natural dialogues.

GPT-5.4 & GPT-5.3: Next-Generation Intelligence in Pipeline Mode

The performance of an AI agent is largely determined by its underlying large language model (LLM). Famulor now integrates OpenAI's latest and most powerful models, GPT-5.4 and GPT-5.3, into Pipeline Mode. These models offer unprecedented intelligence and precision for your AI assistants.

GPT-5.4 – Fact-Based and Precise:

• Maximum Factual Precision: GPT-5.4 is OpenAI's most factual model to date, with 33% fewer factual errors than its predecessor. This means your AI assistants provide more reliable and accurate information.
• Excellent Prompt Following: The model is significantly better at executing complex instructions, sticking to scripts, and managing multi-step conversations. This allows Famulor assistants to accurately handle even demanding tasks.

GPT-5.3 – Speed Meets Intelligence:

• Balanced All-Rounder: GPT-5.3 offers an excellent balance between speed and reasoning capabilities. It is ideal for assistants that need to deliver fast yet intelligent responses.

Practical Example:

An insurance company uses GPT-5.4 for its AI assistant to answer customer inquiries regarding complex policies. Thanks to its high factual precision, the assistant can provide detailed information on coverage, exclusions, and contract terms without making mistakes. Simultaneously, its improved prompt following allows it to execute complex instructions for filing claims or processing applications.

How to Use GPT-5.4 and GPT-5.3:

Select these models in your assistant's configuration under Pipeline Mode. Optimize your prompts, especially for complex multi-step flows that combine tasks like appointment scheduling with real-time CRM checks (e.g., HubSpot or Salesforce). Famulor's No-Code Workflow Builder is the ideal tool for this.

Expanded API and Further Enhancements: Full Programmatic Control

Famulor understands that modern business processes require seamless integration and complete control. The current release significantly expands the API and introduces further optimizations that make the platform even more robust and flexible.

API Expansion Highlights:

• New Endpoints: The API has been expanded with new endpoints for campaigns, WhatsApp, warm transfers, keypad collection, filler phrases, language settings, and provider discovery. This grants you full programmatic control over almost every aspect of your AI agents.
• Custom Integrations: Use the expanded API to seamlessly integrate Famulor into your existing system landscape. Whether it’s a CRM, ERP, Helpdesk, or Marketing Automation platform—the possibilities are endless. Famulor offers over 300 integrations via platforms like Make.com, n8n, and Zapier.

Additional Important Improvements:

• AEC Warmup: A new "AEC warmup" parameter pre-warms the acoustic echo cancellation, reducing audio artifacts at the beginning of calls on Famulor's Voice AI Engine. The result is even clearer audio quality.
• Voice Preview Fix: Issues with Cartesia Voice Previews have been resolved, ensuring that voice samples now play correctly.
• Web Widget Improvements: The web widget has been optimized to improve its mobile layout and the capturing of form inputs upon automatic opening.

Practical Example:

A company can trigger an outbound campaign via the expanded API that calls thousands of leads. After the AI agent successfully qualifies a lead, the lead data is automatically pushed into the CRM system, and a warm transfer is initiated to a human sales rep, who receives all the relevant context right away. At the same time, the campaign can be tracked via WhatsApp to optimize lead nurturing processes.
