Key Takeaways
- A text-to-call converter uses text-to-speech technology to deliver written messages as automated voice calls for reminders, alerts, and notifications.
- Built-in phone features like Apple Live Speech and Samsung Bixby Text Call provide free, one-to-one accessibility options on supported devices.
- Businesses need scalable platforms that handle high-volume outreach, two-way conversations, and regulatory frameworks such as TCPA and DNC.
- Plura AI combines text-to-call automation with AI voice agents, 50+ CRM integrations, and U.S.-based infrastructure that supports compliance.
How Text to Call Converters Work
Text-to-call converters follow a consistent sequence across most platforms. Text flows into a text-to-speech engine, which generates spoken audio. A telephony network, either VoIP or a carrier connection, then places the call and plays that audio when the recipient answers. More advanced systems add two-way conversation handling so recipients can respond by keypress or speech.
A typical text-to-call workflow runs as follows:
- Compose your text. Write the message you want delivered, such as an appointment reminder, an alert, or a follow-up note.
- Choose your recipients. Select the phone numbers you want to call, either individually or as a bulk list.
- Trigger the call. Schedule the call for a specific time, trigger it from a CRM event, or launch it manually.
- Recipient answers. When the person picks up, the system plays your text as spoken audio using text-to-speech technology.
- Collect a response (optional). Some systems let recipients respond via keypress or speech, which enables interactive workflows such as confirming an appointment.
The distinction between a basic text-to-speech output and a full conversational voice AI system matters. Without an intelligence layer handling intent recognition, context tracking, and response generation, a voice system functions like a phone menu with better audio. Basic text-to-speech works for one-way notifications. A full voice AI stack is required for two-way conversations.
Personal Phone Features for Text to Call
Modern iPhone and Android devices include built-in text-to-call features for personal accessibility and convenience. These options are free and require no additional software.
Apple Live Speech (iOS 17+)
Apple’s Live Speech, introduced in iOS 17, lets users type text that is spoken aloud during Phone calls and FaceTime. It primarily supports accessibility by helping users who have difficulty speaking communicate in real time. Live Speech requires iOS 17 or later and an iPhone XS or newer; it is unavailable on iPhone X, iPhone 8, or earlier models.
To set it up:
- Go to Settings > Accessibility > Live Speech.
- Toggle on Live Speech and select a voice, downloading one if needed.
- During a call, triple-click the side button to open the Live Speech window.
- Type your message and tap Speak. The phone plays it aloud to the caller.
Samsung Bixby Text Call
Samsung’s Bixby Text Call converts the caller’s speech into real-time text on your screen and lets you reply by typing, with your typed response spoken aloud to the caller. It is available on Galaxy S24 and newer models with One UI 6.1 or later, and on Galaxy S25 series with One UI 7, where it appears as part of the Galaxy AI feature set. The feature announces to the other party that Bixby Text Call is active and requires an internet connection because conversion happens in the cloud.
Google Pixel Call Screen
Google Pixel devices offer call-screening features that transcribe calls and let you respond with preset or typed text messages. These features live in the Phone app and work automatically for unknown callers.
These personal features support one-to-one conversations on a single device. Businesses that need to send automated calls to hundreds or thousands of customers require dedicated platforms built for scale.
Business Platforms for Text to Call at Scale
Businesses rely on dedicated platforms to send automated voice calls at volume, connect to existing systems, and support U.S. regulatory frameworks. These tools fall into two main categories.
CPaaS APIs (Communications Platform as a Service). Platforms like Twilio and ClickSend provide developers with APIs to build custom text-to-call functionality.4 Twilio’s text-to-speech service offers four voice tiers, Basic (free), Standard, Neural, and Generative, billed per 100-character block. Twilio’s free trial includes 75 voice minutes. ClickSend uses a prepaid credit model with no monthly subscriptions and offers a 14-day free trial with $2 AUD in credits, although ClickSend has sunset its voice service for new signups. These CPaaS options require technical expertise to implement and manage.
AI-powered communication platforms. Platforms like Plura AI provide ready-to-deploy solutions that combine text-to-speech with intelligent AI voice agents. Businesses can configure automated calling workflows in days rather than spending months building from scratch. Plura AI’s complete AI agent platform enables time to first conversation in days, while Twilio’s APIs often require weeks to months of development.
Plura AI’s text-to-call platform runs on Plura’s own FCC-licensed audio bridging carrier rather than a third-party CPaaS. This carrier-level control enables branded caller ID, SHAKEN/STIR verification on every call, and real-time DNC scrubbing before each contact. Plura’s AI voice agents handle two-way conversations and connect to your CRM through 50+ integrations. The platform runs on 100% U.S. infrastructure and supports TCPA compliance, HIPAA, SOC 2, and ISO certification.1

Common Use Cases for Text to Call Converters
Text-to-call converters support a wide range of personal and business scenarios. The right tool depends on the volume and complexity of your conversations.
- Appointment reminders. Automated voice reminders reduce no-shows for healthcare providers, service companies, and financial advisors. A NEJM Catalyst 2025 study found that adding automated voice calls to existing SMS appointment reminders reduced no-show rates from 11.3% to 9.6% across more than 244,000 high-risk patients over 6 months.3 Plura’s platform supports up to 40% improvement in no-show rates for healthcare and appointment-based businesses.3
- Lead follow-up. Harvard Business Review research found that companies responding within five minutes are 100 times more likely to connect with a prospect than those waiting 30 minutes.3 Plura’s AI SMS and voice agents contact new leads in under 5 seconds.
- Order and delivery notifications. Alert customers when orders ship, arrive, or are ready for pickup.
- Emergency alerts. Notify employees or customers of urgent situations, weather events, or service disruptions.
- Payment reminders. Automated payment reminder calls can achieve 2 to 4 times higher contact rates than email.
- Accessibility. Help individuals with speech difficulties communicate during phone calls using built-in features like Apple Live Speech.
Built-in phone features work well for personal accessibility and one-off needs. For appointment reminders, lead qualification, and other recurring business workflows, dedicated platforms like Plura provide the scale, compliance support, and two-way conversation handling that teams expect.

Regulatory Considerations for Text-to-Call in the U.S.
Automated voice calls in the U.S. fall under the Telephone Consumer Protection Act (TCPA), 47 U.S.C. § 227, which addresses the use of autodialers and prerecorded or artificial voice messages.2 The FCC’s February 2024 Declaratory Ruling classified many AI-generated voice calls as “artificial or prerecorded voice” under the TCPA, which connects them to the same consent framework as traditional prerecorded calls.
Businesses running automated calling programs can consult qualified counsel to understand how the TCPA, the National Do Not Call Registry, and applicable state laws apply to their specific use cases. Platforms like Plura support compliance by providing features such as real-time DNC compliance scrubbing, TCPA compliance tooling, immutable consent logging, SHAKEN/STIR caller ID verification, and automated quiet-hours enforcement. Plura’s compliance engine is described in detail at plura.ai/products/compliance. Legal review of your program remains essential.
Frequently Asked Questions
These answers address common questions leaders ask when evaluating text-to-call tools.
Is there a free text to call converter?
Built-in phone features like Apple Live Speech and Samsung Bixby Text Call are completely free on supported devices. For business testing, Twilio and ClickSend provide the trial minutes and credits described earlier. These free options work well for pilots or personal use. Ongoing business use at scale typically relies on paid platforms like Plura that deliver reliability, two-way conversation handling, and compliance support.
How do I turn on text to voice on my phone?
On iPhone, go to Settings > Accessibility > Live Speech, toggle it on, and select a voice. On Samsung Galaxy, open the Phone app, go to Settings, and look for Bixby Text Call (or Galaxy AI > Text Call on One UI 7 devices), then enable the feature. On Google Pixel, open the Phone app, go to Settings > Call Screen, and customize your preferences. All three options are free and built into the operating system.
What is the best text to speech app for calls?
For personal use, built-in features like Apple Live Speech and Samsung Bixby Text Call provide the most seamless experience because they are integrated into the operating system. For business use, Plura offers a more complete solution. Its AI voice agents handle two-way conversations, qualify leads, and integrate with your CRM, while supporting TCPA compliance and DNC compliance on 100% U.S. infrastructure. The right choice depends on whether you need a personal accessibility feature or a scalable business automation tool.
Can you convert a text message into a phone call?
Two main approaches exist. One approach converts an SMS message into a voice call using a text-to-speech gateway that reads the message aloud, which is how business platforms like Plura operate. Another approach escalates an SMS conversation to a voice call, where an AI agent or human picks up the phone and continues the conversation. Plura supports both approaches: its AI SMS agents can text leads, qualify them, then call and live-transfer a warm buyer to your sales team.
How do I send a text-to-speech call to multiple people?
Personal phone features only support one-to-one calls. To send text-to-speech calls to multiple recipients, you need a business platform. Platforms like Plura let you upload contact lists, schedule bulk calls, and track delivery and response rates. Plura’s AI voice agents can handle high volumes of outbound calls while the platform’s compliance engine applies DNC compliance and TCPA compliance tooling to every contact before dial.
With these options and constraints in mind, you can match tools to your volume, regulatory environment, and team capacity.
Choosing the Right Text to Call Converter
The decision usually comes down to scale, integration depth, and regulatory needs. Individuals who need one-to-one accessibility can rely on Apple Live Speech, Samsung Bixby Text Call, or similar built-in tools. Businesses that send appointment reminders, alerts, or lead follow-ups at scale benefit from platforms that manage two-way conversations, CRM connections, and compliance support automatically.
Plura AI serves teams that want AI voice agents, TCPA and DNC compliance support, SHAKEN/STIR caller ID verification on every outbound call, and 100% U.S. infrastructure in a single platform. Contact center leaders, marketing directors, agencies, and franchise systems can centralize outreach while keeping local context.
