02Dictation and voice commandsFast, accurate speech to text inside your app, trained on your vocabulary, with commands that do things rather than just transcribe.
03Call and meeting summariesTranscripts, summaries, action items and CRM updates from calls and meetings, the way Crodo does it for meetings on a Mac.
04Voice assistantsAssistants that listen, can see a screen or a photo, and reply by voice or by taking an action.
05Speed and cost engineeringStreaming replies, interruption handling and the right model for each step, so conversations feel natural and the monthly bill stays predictable.

Voice AI built by people who use it every day

Voice is the interface people already know, and the hardest one to get right: delays, interruptions, accents, background noise and the cost of every second of speech. We built Crodo, a voice assistant for Mac that takes dictation, answers questions about what is on your screen, writes meeting notes and acts in Gmail, Calendar and Slack. Everything we learned shipping it goes into your build.

Our voice AI development process

  1. Discovery, week 1. The calls or commands that matter, a sample of real recordings, the languages, and the rules for handing over to a person.
  2. Prototype, weeks 2 to 3. A working voice agent on a test number or inside a test build, measured on accuracy, response time and how many calls it completes.
  3. Build, weeks 4 to 10. Phone or in-app integration, CRM actions, monitoring, and a rollout you can pause at any time.

Frequently asked questions

Common questions about Voice AI & Conversational Interfaces.

What is voice AI?

Voice AI is software that understands spoken language and responds by speaking or by doing something. It combines speech recognition (speech to text), a language model that decides what to say or do, and speech synthesis (text to speech). Phone agents, dictation and voice assistants are all voice AI.

Which languages can a voice agent handle?

English and Hindi are our daily work, and the speech providers we use support most major Indian and European languages. We test accuracy on your own recordings before choosing a provider.

How natural does it sound, and how fast does it respond?

Every step streams, so the agent starts replying in under a second and can be interrupted like a person. Voice quality depends on the text-to-speech provider; we test two or three with your script and you pick.

Can the voice agent hand a call to a human?

Yes. It can transfer a live call or escalate a WhatsApp conversation with a summary and the caller's intent attached, so your team does not start from zero.

How much does voice AI development cost?

Voice projects with AppWizards usually take 6 to 10 weeks. Phone integration, languages and call volume are the main factors; we give a fixed price after discovery.
