## Gladia

Gladia provides the speech-to-text layer underneath voice products rather than a consumer transcription app. Teams capture audio from live streams, uploads, or real-time microphone input via WebSocket streaming or REST, then receive a clean transcript with timestamped segments. The platform reports hundreds of thousands of users and enterprise teams, and claims top accuracy on conversational audio benchmarks along with leading speaker detection powered by pyannoteAI.

On top of transcription, Gladia bundles native audio intelligence features that are billed only when enabled: speaker diarization, automatic language detection across 100+ languages, code-switching for conversations that mix languages, named entity recognition, PII redaction, sentiment analysis, and summarization. An audio-to-LLM pipeline lets you push transcripts into a large language model, either Gladia-hosted or your own (BYOM).

Integration options include Python and Node.js SDKs, webhooks, Zapier, and 50+ native integrations, plus native meeting-bot support for Zoom, Google Meet, and Microsoft Teams. The company emphasizes enterprise readiness with SOC 2 Type II, GDPR, HIPAA, and ISO 27001 compliance, 99.9% uptime SLA, EU and US hosting, and data-training opt-out by default. A playground, changelog, status page, and benchmark tools are available for evaluation.

**Pricing & Plans:** Gladia uses a freemium model: new developers can start with around €50 in transcription credits that do not expire, and add-on features are billed only when switched on. Enterprise and high-volume plans require contacting sales for custom pricing and SLA terms.

- **Real-time and async speech-to-text:** Stream audio over WebSocket for live captioning or submit files via REST for batch transcription, supporting MP3, WAV, FLAC, Opus, and most other formats.
- **Multilingual with code-switching:** Automatic, accent-sensitive language detection across 100+ languages, including code-switching for conversations that move between languages mid-sentence.
- **Native audio intelligence:** Speaker diarization, named entity recognition, PII redaction, sentiment analysis, and summarization, each billed only when you enable it.
- **Audio-to-LLM pipeline:** Feed transcripts directly into a large language model, either Gladia-hosted or a model you bring yourself (BYOM), to generate summaries and structured outputs.
- **Developer tooling and integrations:** Python and Node.js SDKs, webhooks, Zapier, 50+ integrations, plus meeting-bot support for Zoom, Google Meet, and Microsoft Teams.

**Strengths:** Broad language coverage with real-time code-switching, which many STT vendors lack; Audio intelligence features like diarization, sentiment, and PII redaction are built in rather than chained from multiple providers; Strong compliance posture with SOC 2 Type II, GDPR, HIPAA, and ISO 27001 plus EU hosting; Free starting credits and a public playground make evaluation straightforward

**Limitations:** Developer-focused API product: no simple consumer app for one-off transcription; Enterprise features such as on-premise deployment and some hosting controls are gated behind sales conversations

## Tunk.ai

Tunk.ai is a voice AI platform from LogicNimbus Private Limited, aimed at teams that need to put AI on the phone rather than just in a chat window. The headline product, ANCHOR, is an agent builder: you describe in plain English what the agent should do, who it talks to and what a good call looks like, and the platform assembles the voice, prompts, knowledge and call flow for you. From there you attach tools, endpoints and a phone number, test the conversation, and deploy it either to a live line, inside your own app, or through the API.

Under the hood the platform is organized into six subsystems, covering the call flow engine, a centralized knowledge base, mid-call tools and actions, a unified assistant hub, a workflow engine for branching and escalation, and records plus analytics for every call. Because the agent can call your own endpoints during a conversation, it can book appointments, look up or update records and then write the outcome back to Salesforce, HubSpot or Zoho — analytics then return sentiment, intent and outcome scoring as soon as each call ends. Phone numbers are provisioned through Twilio or Plivo and campaigns can be pointed at a contact list, so outbound dialing runs at whatever volume you need.

The second pillar is speech to text. Real-time transcription returns text while the caller is still speaking, across dozens of languages and accents, and it is available directly through an API or the built-in playground. The platform supports multiple LLM and transcriber providers — including OpenAI and Azure — so you can swap the underlying model without rebuilding an agent. Tunk.ai is listed with NVIDIA Inception and participates in the Speechmatics Startup Program and Startup India. Pricing is enterprise-oriented; the site routes buyers to a demo or sales conversation rather than publishing flat self-serve rates.

**Pricing & Plans:** Enterprise-oriented with a free trial / demo path. No public self-serve price list is shown: prospective customers are asked to book a demo or contact the team, and pricing is reported as per-minute or customized enterprise volume tiers for voice agents, real-time telephony streaming and speech-to-text APIs.

- **ANCHOR Agent Builder:** Describe an agent in plain English and the platform sets up the voice, prompts, knowledge and call flow; then test, refine and deploy to a phone line, an app or the API.
- **Real-Time Speech to Text:** Streaming transcription returns text while the caller is still speaking, covering dozens of languages and accents through the API or the built-in playground.
- **Tools, Actions and CRM Sync:** Hand the agent your own endpoints so it can book, look up and update records mid-call, then write the outcome back to Salesforce, HubSpot or Zoho.
- **Outbound Campaigns and Cloud Dialer:** Connect Twilio or Plivo, point a campaign at your contact list, and let the agent handle every call while you manage only the queue.
- **Call Analytics and Compliance Records:** Sentiment, intent and outcome are scored on each conversation the moment it ends, with transcripts and costs retained so you can audit and improve campaigns.

**Strengths:** Agents are configured in plain English, which lowers the barrier for non-engineers; Covers both sides of voice: an agent builder for calls and a real-time speech-to-text API; Mid-call integrations write outcomes back into Salesforce, HubSpot and Zoho; Carrier-agnostic telephony through Twilio or Plivo, with inbound and outbound support

**Limitations:** No published self-serve pricing, so you must talk to sales before you can budget; Enterprise setup with carriers, CRM and knowledge sources takes real integration work; Public documentation and third-party reviews are thinner than for larger voice AI vendors
