What is audio-to-text transcription?
Audio transcription from voice to text, also known as “speech to text,” is an automatic system that converts messages contained in audio into natural language text.
Advances in Artificial Intelligence and, more specifically, in Natural Language Processing (NLP) and Large Language Models (LLMs) have led to speech recognition systems that enable the automation of converting spoken content into written form with extreme accuracy, giving rise to automatic transcription systems and enabling an endless range of related applications.
Why use call transcription software in your company?
transcribe in real time
Prevent your supervisors from wasting time listening to full call recordings, which are often long and repetitive. Instead, allow them to directly access key information through an intelligent text search tool.
Compliance and Quality
Keep a clear, verifiable written record of every agreement reached during a call: from sales closures to telephone consents. By automatically converting the conversation into text, you don’t depend on interpretations or incomplete manual notes.
AI sentiment Analysis
We don’t just convert voice to text: AI understands what’s happening in the conversation. It can detect the emotional tone of the customer (whether they are angry, satisfied, or undecided) and mark those key moments within the call.

Advantages of recording and converting voice to text
Call transcription is gaining ground across different professional sectors, but many companies are focusing on applying call transcription for human resources, sales, customer service, and marketing teams.
Instant access to crucial information
Thanks to automatic call tagging, you won’t need to replay entire calls to find important data because it will be visible at a glance. Additionally, you can define tags tailored to your business.
Train your team
Transcription enables the analysis of sales conversations, handling of objections, and management of customer relationships. If an agent stands out for their performance, their call transcriptions can serve as a model.
Find the call you need
Call summaries help you identify the call you’re looking for at a glance. Tags, indicating when a specific topic was discussed, show you exactly which part of the conversation to review.
Real-time translation
If you manage global teams, translating call transcriptions into multiple languages allows you to easily access the content of all calls without worrying about language barriers.
Transcribe your voice messages or voicemail boxes
Missed a call? Receive a notification with the transcribed voice message or voicemail directly by email. You’ll save time and be able to read your messages even during a meeting.
Efficiently analyze conversations
Metrics such as keywords used, speaking time vs. listening time ratio, word repetition rate, topics discussed, and other elements that allow you to measure efficient communication parameters.
Designed to empower every department
Customer service
The system automatically analyzes call transcriptions to evaluate operator performance without the need to review audio recordings one by one. It can scan large volumes of conversations in seconds and detect alert keywords such as “unsubscribe,” “complaint,” “claim,” or any other risk indicators you define.
Sales and Telemarketing
The system automatically evaluates operator performance by analyzing call transcriptions in seconds. Instead of reviewing full recordings, it can scan the text and detect alert keywords such as “unsubscribe,” “complaint,” “claim,” or any other critical signals defined by the company.
Legal and Compliance
Have peace of mind with a fully traceable and easily auditable textual record of all conversations. Every call is documented in an accurate way, allowing you to demonstrate what was said, when it was said, and in what context.
Trust audio-to-text call transcription to improve sales, customer service, and marketing.
Real-time call transcription that integrates with your tools
Optimize your workflow by automatically syncing each audio-to-text transcription with the tools you already use.

Ideal for audits and retrieving critical customer information.
Boost your sales with real-time automatic transcription of video calls
Transcription of video conferences and sales calls allows you to have all data from every conversation with all prospects or customers in the company’s CRM. You will have all relevant information gathered during customer interactions without missing any detail.
Conversation analysis: audio-to-text transcription allows sales representatives to review their dialogues with customers and prospects to discover and retrieve information about the interlocutor’s needs and expectations, adjust their pitch, and explore new sales strategies.
Training and development: as a sales leader or manager, call transcription can enrich your coaching and listening tools for training and development. It allows you to identify growth opportunities for your employees and help them reach their full potential.
Documentation and storage: automatic transcription is also an excellent way to maintain a written record of all interactions with customers and prospects, ensuring that you don’t forget anything crucial for retaining a customer or closing a sale.
Protect your company with call transcription
Automatic tagging and AI transcription not only optimize customer service, but are also essential corporate cybersecurity tools.
Fraudulent interaction detection (Vishing)
The transcription engine scans the call content in real time. Through alert tags (risk tags), the system detects anomalous patterns or keywords associated with social engineering or identity impersonation attempts (phone phishing or vishing).
Audit and Data Protection (DLP)
Converting voice to text enables the application of Data Loss Prevention (DLP) policies. Automation facilitates auditing and the identification of leaks or mishandling of sensitive information (PII), ensuring compliance with strict corporate security regulations.
Call summaries: from voice to actionable data with AI
Call transcription is only the first step. The real value lies in automatic call summaries, capable of extracting the key points of each conversation in seconds.

Frequently asked questions about recording and transcribing phone calls
Everything you need to know about automatic call transcription with Fonvirtual
How accurate is the transcription?
Transcription is highly accurate thanks to our speech recognition and natural language processing system. It recognizes accents, jargon, and technical terms, although accuracy may depend on call quality and on how well the system has been trained with your company’s own vocabulary.
Can it be saved or analyzed after the call?
Yes. All transcriptions can be securely stored to generate reports, perform quality analysis, train virtual agents, and maintain a complete record of customer interactions.
What languages does real-time transcription support?
Fonvirtual supports all or almost all languages, including Spanish, English, French, German, and even Chinese. Additionally, it recognizes different accents to ensure transcription is as accurate as possible in multilingual environments.
Can information within transcriptions be searched or filtered?
Yes. You can search for keywords, topics, or customer names within any transcription, which makes it easier to analyze trends, detect recurring issues, and gain insights without having to manually review each call.
Do transcriptions integrate with our CRM (Zendesk, Salesforce, Zoho...)?
Absolutely. The main advantage of B2B call transcription is that, once the conversation is finished, the full text (and the AI-generated summary) is automatically attached as a note in the customer record within your CRM. No more manual notes.
Does transcription work in real time during group calls or conferences?
Yes. Fonvirtual technology can transcribe calls with multiple participants, distinguishing between speakers and maintaining content clarity, ideal for meetings, conferences, or calls with more than one client.
Is transcription done in real time or when hanging up?
Both options. You can see how voice is transformed into text tiempo real on the agent’s screen (ideal for call centers or simultaneous translation), or you can configure the platform to generate an automatic AI summary as soon as you hang up the call.
What is the difference between recording calls and transcribing calls?
Conventional recording forces you to store hours of heavy audio and listen to it minute by minute for supervision. By automatically converting calls to text (transcription), you get an indexed document where you can use the search tool (CTRL+F) to find the exact 10 seconds where the customer says «buy» or «complaint», saving thousands of hours of supervision for the call center.
