A voice agent can understand a menu perfectly and still fail when it presses a key. Dual-tone multi-frequency (DTMF) reliability depends on tone transport, timing, call state, carrier behavior, and proof that the interactive voice response (IVR) system accepted the input.

TCPA risk in voice AI turns on the campaign: who is called, why, which technology speaks or dials, what consent or exemption applies, and which controls preserve proof. A platform cannot make that campaign compliant.

Knowledge-based authentication (KBA) can reduce repetitive verification on voice calls, but it is a weak standalone security boundary.

Speech-to-speech models can make a voice agent more responsive and expressive. The category label also hides an important architecture choice.

Voice activity detection looks simple: label each audio frame as speech or non-speech.

An AI agent can turn one bad model response into an account change, message, booking, or API call. That makes agent security an architecture problem for any team giving models tools, memory, or access to business data.

Moving a phone operation to the cloud often exposes a hidden dependency: the software platform also wants to become the telecom provider. Bring Your Own Carrier (BYOC) separates those decisions.

A white-label AI voice agent can put your brand in front of clients within days. The harder question is what sits behind that brand.

Multi-speaker text to speech can mean a model able to produce different voices or a workflow that actually renders more than one voice. That ambiguity leads teams to choose the wrong architecture. The practical question is whether you need a static scene, an editable sequence of turns, or a live conversation. Each requires different controls for identity, timing, latency, and quality assurance (QA). Here is how the pipeline works, which implementation patterns fit each job, and how to test one before production.]]> https://dasha.ai/blog/multi-speaker-text-to-speech multi-speaker-text-to-speech Thu, 07 Oct 2021 12:49:08 GMT multi speaker text to speech, multi speaker TTS, text to dialogue, multi voice text to speech, speaker embeddings, dialogue synthesis 14 minute read

An in-car voice assistant has to understand speech through road noise, respond before the exchange feels broken, work through poor connectivity, and keep conversational AI away from unsafe vehicle actions. Those constraints make it a different engineering problem from adding a microphone to a mobile app. Here is the architecture, interaction model, safety boundary, privacy program, and test plan technical teams need to build a production system.]]> https://dasha.ai/blog/voice-assistant-for-cars voice-assistant-for-cars Wed, 30 Jun 2021 18:51:40 GMT in-car voice assistant, car voice assistant, automotive voice assistant, voice assistant architecture, voice AI for cars, embedded voice assistant 18 minute read

Choosing between synthesized and pre-recorded speech affects far more than voice quality. It changes what your voice product can say, how quickly it can respond, how safely teams can update it, and what happens when a dependency fails. The right design starts with the content each utterance must carry and the conditions under which people hear it.]]> https://dasha.ai/blog/synthesized-vs-prerecorded-speech-for-voice-ai synthesized-vs-prerecorded-speech-for-voice-ai Fri, 30 Oct 2020 13:02:58 GMT synthesized speech vs prerecorded speech, live TTS, pre-generated TTS, synthesized speech, pre-recorded speech, text to speech, voice AI, recorded voice prompts, hybrid voice architecture 11 minute read

Average call wait time looks simple until dashboards disagree about what starts the clock, which calls enter the denominator, and whether callbacks count. Those choices can make a queue appear healthier while more callers abandon. A useful measure needs a fixed definition, a companion service-level view, and quality guardrails. Here is how to calculate, diagnose, and reduce queue delay without confusing it with hold time or average handle time.]]> https://dasha.ai/blog/average-wait-time average-wait-time Fri, 04 Sep 2020 10:40:15 GMT average call wait time, average speed of answer, call center average wait time, average wait time formula, reduce call wait time 9 minute read
